My friends and I are looking to plan a trip this summer to stay at various parks for a few days each. We are from houston and want to stay around the central texas area. We want to swim/tube/fish and probably a little hiking (you know just a relaxing trip). Ive been to a few parks before and want to go back. Anyways im looking for any help I can get in planning a good camping trip around central texas.

Heres an outline of what I was planning:
I was looking at starting the trip off by going to Guadalupe River state park for a few days (Can anyone suggest a good river tubing company?). After that we were thinking about heading over to Garner State park (very beautiful). Then we planned to head to Kerrville State park (Ive never been there, pro and cons about it?). Then go up to Pedernales Falls for a day or two. For the final leg we would either stop at schlitterbahn down in New Braunfels or head home.

Any amazing parks I missed out that you suggest I go to? Which river is best to tube on? Can you suggest a good tubing company? Thanks for the help!
