We've had several people suggest the late play tickets. We'll definitely have to hit that up. Nat'l Gallery, Tower (I like the night-time idea, thanks), Eye, Imperial War Museum (Great idea, thanks!), Hyde Park.

All fantastic, and even some new, ideas.

Thanks guys.

I don't care much about celebrities and such. Is Tussaud's worth it?

As for meals, we are fortunate enough to have a kitchen where we are staying. That's one reason we went with an apartment over a hotel. We would like to cook in a few times, if for no other reason than to save money. Breakfasts will probably all be cooked by us. Most days we probably won't be around for lunch or dinner. The books we have suggest ways to find cheaper food, such as small lunches at pubs and the like. Does anyone have any tips for that? We do plan on spending money on, at the least, one good meal, but we definitely can't afford that every night.

Thanks!
