My grandparents lived in Ft. Myers for decades, so I am familiar with that part of Florida. We'd love to camp at Long Key State Park one day -- we visited there when we were renting a small cottage on Conch Key (to sail daily on a lovely little 19-footer). We used to own a Catalina 30 but never lived aboard.
We are planning to tow our Honda CR-V so want to stay under 30' for our motorhome if we possibly can, but I agree the 2910 is a lovely floorplan! We definitely want either twin beds or a walkaround queen -- we could not live with a side queen because of one of us having to crawl out over the other in the middle of the night to potty. That would be a dealbreaker.
