A few years back we went to Florida with a cousin. We were to stay 14 days in FL and he was as excited as either me or my wife upon departure. Upon arrival his demeanour changed and he was moan this, moan that for a solid 2 days. From weather to the food. I convinced him (for lack of a better word) to visit a family member of his in Orlando. Next day took him to airport for a 7am flight and we went our separate ways. We are still in daily contact today and do not begrudge him but there was no way I am doing a holiday with that kind of behaviour.
