First it sounds like you did an amazing job raising your child. I too have a soon to be college bound child. If my son was in this same situation I would strongly encourage him to take the full ride. At least for the first two years. So many of the classes are required classes outside of their major field. I transfered after the first two years of my college years into the college I graduated from and I am glad I did. What I thought was going to be my major ending up changing too. The cost of college and text books is so high that having this gift of a full ride is one to not be looked upon lightly. It doesn't hurt to try the college with the scholarship and transfer out after the basic classes are covered. Good luck with your decision!
