Hate to do it, but would be upset if someone had my experience and did not warn me. This unit made me sick. Watery, scratchy eyes, swollen throat, swollen face. As points of reference, 50 yr old male, relatively healthy, no known allergies, experienced US traveler (366 Marriott nights), work in industrial environments. In other words, I am not what one might call environmentally sensitive. The place is newly renovated. Nice, pictures accurate, loved the (2) golf carts, tons of room. Great location, 3rd stay in Sandpiper loop. But as the week progressed, it became obvious I wasn't experiencing a cold, allergies or hang over. The reaction would subside 30-45 min after leaving unit. The unit developed a noticeably stronger smell as the week went on - it permeated everything. So bad, the luggage in vehicle smelled / made me sick until we got home and away from or washed everything that had been in the house. Wont speculate and my companion who does have allergies and is more sensitive, was irritated by the smell, but she didn't develop the reactions. But if you or your kids experiencing what is too easily written off at the beginning of your trip as a cold or simple allergy - see what happens when you get fresh air for an hour. Don't unknowingly make yourself miserable, rationalizing the issue away, like we did.
