Vacation Help

Options
I just started on Monday, and want to do a good job even though I am going on vacation for 5 day this weekend, visiting friends I don't get to see often and having a good time.

Hoping for vacation eating tips, to try and keep within the realm of healthy while away from home. Obviously drinking is calorie consumer, and eating out as well. I will be walking a lot, sightseeing and around the city, so I'm not TOO concerned about exercise for the weekend.

So far I have:
Bring Plane/Day snacks and low calorie items to have so I don't have to buy bad stuff while out and hungry
100 calorie packs, fruit, low calorie snack bars, pretzels, etc...
Salads with dressing on side (at restaurants) Try for 1 a day
Drinks- vodka/soda/ lime or cranberry OR Bacardi/diet coke Trying not to drink a lot, but still go out and have fun
I'm also not eating dairy which may help with dinner menu options
