While I've never been to Hutchinson Island, I do go back to Marco every year. My girlfriend and I went to St. Thomas in the US Virgin Islands last week, but I feel so strongly about our yearly trip to the Marco Island Marriott that we are still going in May. The service is above and beyond what I've seen elsewhere. If you go to Marco, you won't be disappointed. Make sure you and the wife stop by Kurrents...the steak is awesome.
Sincerely,
Matthew Gulino
