Mama and Papa Straggler are off on a jolly package holiday to Cuba quite soon. Part of it entails sleeping out on a verandah for some reason (don't ask, cos I don't know!) so they asked me about thin sleeping bags. I'm guessing that a cheap 2-season jobby would do the trick, and was thinking of popping to Go Outdoors or Sports Direct to pick up a couple of £20 things. But I've never been to Cuba and don't know how cold it gets, so some extra advice would be nice thanks!
