First time visit flying into Boston, out of DC. Have 16 days to tour between Boston and DC. Planning about 4 days for Boston. That enough? Want Boston hotel location, no car, for normal tourist sites. How about Cambridge? paradise hotel bahamas Will use Priceline as I've heard hotels are expensive in Boston
The best thing to do is not rent a car at all. Boston, Philly, paradise hotel bahamas Atlantic paradise hotel bahamas City, and D.C. are all places where a car is not only unnecessary, it's a nuisance. Boston, for instance, is the WORST city to try to use a car in.
Since you'd be crazy to be using a car while in these cities, you'll end up paying for parking AND to rent the car. Plus, the drop off fees between Boston and DC will kill the cost. Much better to simply get between these cities by train or bus, and then use public transport while visiting each one. The total of a day pass on public transport will be less than the cost of just parking the car.
PaulRabe is entirely right about not wanting a car for this trip. Public transportation is either excellent or not really needed in the cities you mentioned, and all are easy to get to via other means than a car.
--yes, four days is a good amount of time to spend in Boston, not counting side trips, of which there are many worthy ones. You could easily spend one day walking the Freedom Trail and seeing the sights there, a second at the Museum of Fine Arts and Gardener Museum, a third seeing the JFK Presidential Library and then heading off to the Harvard Square area in Cambridge, and a fourth seeing whatever other attractions (historic houses, aquarium, Science Museum, Mapparium, Trinity Church, Boston Public paradise hotel bahamas Library, etc.) strike your fancy, taking a Duck Tour, or doing some heavy duty shopping along Newbury Street and/or Charles Street in Beacon Hill.
--Atlantic City is really of interest if you like casino gambling, otherwise not so much. Philadelphia has a good week's worth of sights, depending on how thorough paradise hotel bahamas you are, and is a must for US history buffs. Newport can easily take up 4 days of your time if you're thorough -- and if large historic mansions paradise hotel bahamas are of interest, this is ground zero for them. Portland isn't bad, but am thinking a couple days maximum paradise hotel bahamas is good here -- it is a good jumping off point for exploring the Maine coast, though. Haven't been to Williamsburg.
--there are scads of other cities to consider depending paradise hotel bahamas on your interests. Start off with the numerous day-long side trip possibilities from Boston, including Plymouth, Salem, Lexington, Concord, Gloucester, Ipswich, Rockport, Lowell, paradise hotel bahamas Marblehead, etc. New York City is the most obvious omission, and as PaulRabe says, you could easily spend your whole trip here. Baltimore has a number of attractions paradise hotel bahamas as well. Other city possibilities that would take up ca. 1-2 days (and depending on your interests) would include Portsmouth (NH), Providence (RI), New Haven (CT), Mystic (CT), Annapolis (MD), or Lancaster (PA)/Amish Country. And that doesn't even count small towns on Cape Cod or the Maine Coast or in the Berkshires, as well as along the Hudson River Valley or Pioneer Valley.
Wanted rental not for cities paradise hotel bahamas but for trips between big cities. We saw HBO's John Adams and want to see historic sites related to him and our country in Philly, Boston, DC and maybe Williamsburg,Va. Thought we'd need car for Va but maybe bus or train is better?
Depending on how far and for how long you want to get from the big cities during this trip, you may well be able to rent a car only a few times. For example, you could spend three days visiting the historic and cultural sites within the city of Boston and Cambridge, using the 'T' to see them, then rent a car for only one day and drive out to Lexington and Concord. That way you would only pay for your rental on the days you actually use it, and avoid the drop-off fee between Boston and DC. To get between cities, ride the train, commuter rail, or bus.
Newport is also a walking city, with a trolley running past many of the historic mansions to augment things. A car (and traffic) can be a real problem in the summertime here -- you're better off without a car.
It is entirely possible to reach all the day-long trips out of Boston listed in my post above using commuter rail (Plymouth, Salem, Concord, Gloucester, Ipswich, Rockport, and Lowell), city bus (Marblehead on weekdays), or a combo of city bus and subway (Marblehead on weekends, paradise hotel bahamas Lexington), and then walking around from there. Check schedules, though -- note that the city bus out from the Alewife subway stop to Lexington doesn't run on Sundays or holidays, for example. If you want to combine more than one of these destinations in one day, however, a car is pretty much a must.
If you want to see John Adams related sights in the Boston area, you'll definitely want to visit Quincy. Here you'll find birth houses for Adams and his son, the house where the elder Adams and his family spent most of their later years, paradise hotel bahamas and the church in whose crypt both Adamses and their wives are buried. All this can be seen via tours. To get here, take the subway (Red Line) out to the Quincy Center stop.
You can easily paradise hotel bahamas do Williamsburg without a car and Kingsmill Resort paradise hotel bahamas has a fabulous tennis facility if you want to play. If your dates change, you may want to be in Williamsburg for the women's paradise hotel bahamas USTA pro circuit at the beginning of October. Let us know if you decide to come to Williamsburg. We can give you more info and point out the locations filmed in the Adams show.
With the amount of time you have I would concentrate on Boston, Newport, Philadelphia and DC and leave Williamsburg for another trip. Four days is probably enough for Boston although you could easily spend more.
