To start, staying at Gullwing made for one of the best vacations we had. The property is very clean, and it is within walking distance to several shops/restaurants as well as a trolley stop right near the entrance for more distant excursions (maybe the front desk could offer purchasing passes?). Also, the beach access is AMAZING. The staff is great and very helpful. We had to check in after hours AND check out after hours due to our flights and the staff made the process very easy.
I realize that maintaining a resort property takes a lot of work, which leads me to the noise. Through the week we were frequently wakened with the chorus of leaf blowers, weed eaters, dump trucks, a truck delivery, and the sidewalk out front was under construction/repair. It really wasn't a big deal for us but it might be for some people. The noise was only in the morning though. The evenings are generally quiet unless the people in the resort adjacent are partying too loud.
The other detractor was the pool hours. The posted hours are "8 am-dusk" but in the fall the dusk is a relative term. There were many families at the resort and the pool area is well lit in the evening. I think it would be easier and safer to have a set closing time (9 pm?) at which time the gate is secured.
All in all, we would highly recommend Gullwing for a great Ft. Myers beach vacation! We had a wonderful time and plan to book it again in the future.
