Is it better to show a rent of £60 for 2 guests, then add £20 for a third guest using the single bed or show a rent of £80 with a reduction of £20 if only double bed used? thank you.
This can turn into a right nightmare, @Carol6630, as you'll have the whole 'we're together but don't sleep together' stories (many of which will be true). Personally, I'd go for 'extras' to include additional guest(s). But that doesn't rid you of both beds being used for solo sleepers. It's a minefield!
