Whoo hoo!! Finally something I actually know about!! I work in Marriott reservations so I'm PAID to know about the hotels in this area!! Of course my information is a little biased so Ill try to stick to the impartial things that I know!
I think that if you aren't used to driving in a city you should definitely stick to either a downtown hotel, or a hotel in the suburbs that offers shuttles to the metro. But honestly guests tell me that driving in DC is no worse than any other city, it just gets a little confusing with all the traffic circles!
Of course the farther into the city the higher your rate might be, but another thing to watch out for is high parking costs. Spending 20$ a day on parking and not even being guaranteed a space can put a damper on your vacation!!
I recommend staying right outside the city as well if you are looking at staying for a low rate, but as far as convenience goes you can't beat staying at a downtown property!
When you call make sure you check for all available discounts! Some of the best ones are government rates (Marriott gives government rates to Federal AND State and local governments!),
AAA sometimes has a good rate but it's based on availability and sometimes it's only a couple of dollars off. If you have an American express card, Marriott has special weekend promotions and rates can be as low as 69$/night on weekends!
I could go on forever!!
I get to stay at any Marriott hotel in this area for free so I've stayed at a lot of them my favorites are:
∙ The JW Marriott on Penn. ave.- The spa is GREAT! You wont want to leave the hotel! And they have an awesome buffet in the morning!
∙ The Crystal Gateway- It has a metro stop right in the hotel, you pay a bit more than you would at other hotels in the area but the convenience more than makes up for it!
∙ Ritz Carlton DC- Ritz Carltons are known for their luxury so you can expect to pay a lot for them unless you have a government rate.
When you make reservations you should check to see if the hotel offers a shuttle to the metro.
Well good luck on your hunting!! And have a great vacation!
