I live about 5 to 8 mi from the 2 RV courts -which I think you are referring to..if they are on that peninsular that juts into the Gulf right near town of Cortez. I am unable to scare up anything in the area.. Have stayed on Treasure Is. self - (it seems a bit far to go back & forth from) St. Pete area is MUCH closer -like 'st. petes Beach. There is a great resort called Tradewinds with (some timeshare units) but mainly glorified hotel -at the side is a connected business called Guy Harvey Outpost..where they have the biggest aquarium tank in their restaurant that one is dwarfed by creatures like beluga whales, etc Look into Tredewinds it is run by blue green, and has had rentals advertised on redweek.
If all fails -cont make a mistake and try Tampa...no T/S except one that caters to non-straights.
My fav resort in Johns Pass area is All Seasons - but they are all 2 bdroom. 1 pool. Bubba Gump and a very good busline going into St Pete proper.
I hope you don't mind.. but unless you can get a rm at the Holiday Inn on Coertz, you would be traveling a long way back and forth. I have not looked, but maybe a Hampton Inn exists around here, as the HOL. iNN doesn't give free bkfsts like the H. Inn EXPRESS and the Hampton do.
Good Luck .. Am sending off a PM to you too. Curious how far North you live, and if you are flying or driving self.. Cheers- Bev Hook
