We spent the 2009 Christmas holiday at Collier-Seminole State park. It is conveniently located less than 10 minutes from Marco Island, and about 20 minutes from Naples beaches, and Less than an hour from Shark Valley (a must see in the Everglades). Collier-Seminole offers some excellent on site canoeing (including alligators), and the staff at the park are extremely helpful and hard working. We have a large RV and were fortunate to be in one (of about 10) spacious sites, however, before you book your site, you will want to check the camp-ground map. This park is Waaaaaaaaayyy too crowded. If the park service removed every other site, the camp ground would still be too crowded. Our experience with every state park we have traveled & stayed provided plenty of space between camp sites. It is not the case at this park. p.s. don't forget the mosquito repellent!
