Ok, My family has finally decided on St. Louis as our family trip this summer, but I need some help. We are staying close to home because of the price of gas and the rising costs of everything else. We are planning on going to a Cards game, the arch, city museum, the zoo, the science center and six flags. How many days should I plan to see all of these things? Where is a great budget place to stay? Where can I get the best discounts for the things that cost? I also need recommendations for the best places to eat on a budget. Am I missing out on any other must see places? I would appreciate any help that anyone can give.

TIA
Jennifer
