I have only been on an all inclusive twice. once was a last minute "teletext" booking in Kenya Ivory Coast. Good fishing, didn't like owt all else, even the weed was shite, lucky I had some back up. The next one was one of my brothers weddings in Cyprus and other than loving my family, I hated it.
Being fairly well travelled, I usually wing it. Flight, cash/card in the pocket, fishing gear (that has been more of an issue recently) and bosh!
Love a camper van. I have a high top Transit with a bed in the back, fridge, food making equipment and a bucket to have a piss in if needed.
