At the end of July we'll be moving to College Station, TX. We are two adults, a three-year old and a four-month old. We have four days to do the trip, so we are really not in a hurry, but we would also like to use this opportunity to stop at interesting/nice places both to sleep and for the three-year old to run around. Any suggestions about must-see attractions, parks, or anything that we should visit? Suggestions on places where to sleep?
