Possibly. It would be best to have your daughter contact the park. I'm thinking that she could arrange for you to be her guest. However, each military RV park is a little different. If not at Fort Sam she could try other military installations in the area. There are a couple more military RV parks in San Antonio area. Check out https://www.militarycampgrounds.us/milcamps for others in the area. Good luck and plan ahead. Fort Sam is a busy one but very nice.
