If you are looking to rent on Marco Island, this is the condo for you. My family just returned from a couple of weeks in Lorraine's unit in South Seas on Tigertail Beach. It was our best vacation in Marco so far.
We love Tigertail - it's right out the door with remarkable shelling and the opportunity to be off the beaten path in no time if you want some quiet and solitude in nature. There are volumes of wildlife around, including tons of birds, because of the natural areas to the North of the building.
This unit faces the beach with beautiful sunsets, and a view of the pool (which we liked as our family often divided up - but we could find each other easily). The deck is in the sun and has nice furniture in great condition - and plenty for about 6-8 people.
South Seas keeps the pool about 83-86, which makes it an option even on a cloudy or breezy day. We used it every day of our vacation!
Lorraine's unit is well maintained, and you can tell they care about their home away from home. We felt very comfortable. The furnishings and fixtures felt more like a vacation home and less like a beach cottage (i.e. more like something you want to sit on than something that could be covered in sand). At the same time, we have a 3 and 5 year old and nothing was too fragile or frightening for us (which is sometimes a concern, as you might imagine!)
The unit is the most well-stocked we've ever experienced as well. Everything from beach equipment (chairs, cart, umbrellas, sand shoes, toys, fishing and shelling gear) to household basics (loads of dishes, great pots and pans, bedding (including the possibility of sleeping another 2 people), even kid-sized cups and utensils) to rainy-day supplies (puzzles for all ages, books, movies, and games).
Lorraine (the owner) is outstanding to work with. She moved around some personal plans to make this work for us; was in contact with us before, during and after our stay; and when a couple of things went awry in the unit (little details like a cracked handle on the sliding door), she gave us easy resources to remedy them.
I would rent any unit from Lorraine again in a heartbeat. And if you have a chance to stay here, you won't be sorry!
