Your prefered place
A resort in a private island is great.
There are some marvellous places for it, like the Maldives in the Indian Ocean. Small islands with one hotel each at the island. You can walk round the whole island in say 25 to 40 minutes (the islands vary in size of course). Fine sandy beaches, coral reefs, the snorkeling is fantastic, high standard of hotel (from standard to luxury). Officially nudism is not allowed, but in practice swimsuits are not used much. At least at the resort I visited some years ago. If any of those resorts changed officially to a nude resort, then it would be the perfect holiday paradise for nudists longing for a relaxed, sunny and warm getaway.
My preferred place to stay:
Hmmm.
I have been on a private island twice for long weekends, on an island on Loch Lomond north of Glasgow in the foothills of the Scottish Highlands.
A landed club, that is a naturist club that has a small part of the island, its not a resort, but it is a beautiful place and the members of the club are very welcoming, the only way to get there is by a 20 min boat trip. If you are in Scotland I recommend it.
Jungle no, but I have stayed in two Naturist sites around Bergerac, South West France, both are really good sites, owners are very welcoming, and I am going back to one of them again this summer
Beach, well yes been to Charco del Palo on the island of Lanzarote, off the African coast,
It is a clothes optional village and coat line, no real beaches there,
A quite resort, ideal place to relax and unwind.
As yet I have not been brave enough to go to a beach in the UK.
My answer would be which ever is the warmest and sunniest and the quietest, oh and the cost, hehe.
