What's your target daily budget?

I'm coming off some UK/EU travel and, for three of us, we were burning a solid $300/day for hotel, food, entertainment (cheap museums, mostly) and incidentals. The worst part is that the hotels we stayed at were probably a notch or two lower than I'd have liked, trying to economize.

I'm planning out another trip to Copenhagen and Amsterdam for next fall, and am just throwing $200 a night at the hotel number in hopes of being close, but even that turns up few options in/near the cities.

What are you all seeing in your travels? Do you have a target number you try and hit?
