We're trying to go to the beach this weekend w/ our 2.5 yr old and 4 month old, hoping it won't end in disaster.

We live about 1.5 hours from the beach and want to get there 1st thing in the morning. We're in TX, so it's super hot and humid (but cooler at the beach). We plan bringing a tent, chairs, cooler w/ snacks and drinks and beach toys. Our 2.5 yr old still needs one nap, so we're trying to figure out if we should attempt it there or on the way home.

What are some tips you have for surviving and making it fun?
