Use to stay down in Naples area all the time for work - I never stayed at the Hilton on Marco Island but did stay at the marriott - fortunately, it was a very low rate or I would have been very upset - there were roaches in my room! Hopefully the Hilton is much nicer. Personally love the SW gulf coast area - lots of wonderful restaurants, people are nice, etc. As I recall, summer is off season so you might want to check the rates - sometimes they can get very unexpectedly low down there and you might prefer to pay for some nights than to burn alot of points. If you can get a good rate for a night at the Hyatt Resort - its a gorgeous property you might want to check out.
