It is about a 10 min walk to the grandstand pool, 15 to 20 min to springs pool. I actually liked the walk, nice walking trail thru beautiful grounds. Harder if you have small children though.
I guess it really depends on the family though, are you the type of family that needs to get everywhere fast and convenient or are you more of a leisurely family. I think the THV's are more for the leisurely type families.
