I was reading the 'rules' for these tours. I understand the not bringing food, etc. It also says no backpack or purse, so I'm confused on how I would arrange a tour only carring a drivers license! Any one who has done the tour, please give me some tips. Thanks!
For the White House, which is the only REALLY strict one, you are allowed to carry a wallet, a phone, glasses, and an umbrella; that is it. Essentially, wear something with pockets, because that is how you will have to carry them, unless you hold them in your hands. (Not all that outrageous, really; men manage with this much every day.) On the other tours you can carry a handbag, but it will be subject to search. (Note that WH tours now require advance security clearance, and the wait list to process than and get into the tour is normally about 6 months out, unless you know someone in government who can pull some strings for you. We have not been since 9/11, because we can't plan trips that far in advance.)
If you are going to the WH, staying
in the District is the best option, because you can return to your room to fetch your stuff after the tour. If that isn't an option, the second-best choice is to put all your stuff into one zippered tote bag, then visit the Bell Services desk at one of the (relatively) nearby large convention hotels and check the bag while you do the tour. A generous tip will almost always make this possible, but be aware that almost every hotel in DC will reserve the right to search any bags (or automobiles) that they accept into short-term storage.
Going to the WH with a child in diapers isn't recommended, but if you absolutely have your heart set on going, the only way to manage the diaper issue is to double-diaper the child before the tour begins, because you are not allowed to carry in diapering supplies.
PS: Investing the extra $5 in a SmarTrip card for each visitor can help to save your feet. Unlike the Metro-only visitor passes or regular Metro tickets, SmarTrip cards can be used on the regular city buses in the District and the MD/VA suburbs, and on the DC Circulator buses. (However, be warned that the DC bus route maps are so obscurely drawn that you'll almost need help from a CIA cryptographer to figure out which bus goes where.) On a recent trip my family used buses extensively to supplement the Metro and save a lot of walking; our transit total for a 3.5-day trip was right at about $23/each, plus the $15 we paid up front for the 3 blank SmarTrip cards; we were staying in Pentagon City. (SmarTrip cards are good forever, so if you buy them, keep them, register them, and put them away for the next trip.)
If you plan to stay in the far 'burbs, weigh your hotel cost savings against what your Metro tickets will cost you; trips in from West Falls Church to the Smithsonian stop, for instance, will cost $4.25/pp before 9 am on a weekday.
Also, remember that food tends to be one of your two largest expenses in DC. A hotel that provides a full hot breakfast will give you an avg. food cost savings of $12/pp/day, and if you eat a big breakfast you can often manage to just skip lunch and go straight to an early dinner; also, it saves precious touring time, too. IMO, it is worth it to pay a bit more for your hotel if they feed you. In our family, we value a good hot breakfast buffet at around $50/nt.
