Our family of 6 (including 4 sons) really enjoyed North Captiva. The house is very well appointed and we weren't lacking anything on the trip. Charm helped us plan for the week on the island and prepared us for pre-ordering groceries, booking the ferry & taxi and organize the many fun things to do.
Upon arrival, Charm and Brian walked us through all of the details of the house, from charging the golf cart, using the pool amenities, navigating the kitchen and entertainment system, etc. We felt cared for from the moment we arrived. They even checked in on us during the week to make sure we were managing well.
About the island: North Captiva is offshore and away from the typical beach noise and activity. If you need/crave entertainment (e.g. restaurants, mini-golf, shopping, etc.) don't come. If you want to spend quality time with your family, come. We kayaked, road bikes all over the island, swam in the pool, fished from the shore, did an island scavenger hunt, looked for sea shells, explored every road with the golf cart, visited the manatee's every day, did all 3 puzzles, 3 games of Monopoly, movies when it was hot, etc. Every hot spot (Mangos/Barnacles) were no more than 3-4 minutes by gold cart so we could easily find one-on-one time with our kids without going too far away. BTW, the pool is in the shade from 8-noon and again after 4. The location of the giant palm tree and home was brilliantly designed to eliminate the need for sunscreen for most of the day.
Only bummer from the week was Red Tide. Check it before you come to make sure it's not at peak season. We didn't spend nearly as much time on the beach as we ordinarily would. That being said, the pool was a welcome respite and provided needed relief from the heat.
