There is a professional golf tournament held each fall in Disney World, and they play on the Palm and Magnolia courses. The final round is held on the Magnolia, so that would lead me to believe that is the more prestigious of the two.
I am sure if your BF is a golfer he would love to play either one, but just check your dates. I am pretty sure the tournament I mentioned is played in October! That would pretty much leave those two out if it is during the same time! On the bright side, he could go watch some pros play!
If by some chance they are playing the pro tournament when you are there, a short cab ride away is Hawks Landing, surrounding the Marriott World Center. That is one heck of a course!
