how much time can you take off, op? if we are talking a full week, i'd do a staycation - 5 yr olds don't see a difference between the national zoo and going to philly to that zoo

i'd plan an activity a day - ideas-- indoor pool, movies, monster mini golf, zoo, smithsonian museums, great falls. You will have a little more wiggle room with your cash by not paying for a hotel and road trip gas, so you can treat to things like an ice cream, a stuffed animal at the zoo gift shop. have fun - we have had some great staycations - we always shake it up, breakfast for dinner, faux camping in the living room, breakfast in bed, etc.
