So Sofa beds are a matter of opinion. I didn't do the one at SSR but the one at GF. let me put it like this, for one or two nights it was fine by night 3 after walking the parks it was seriously uncomfortable. by the 4th night we were rotating beds so no one would be stuck on it for more than a night or two.
lol, if there is a kid in the party, stick them on the sofa bed.
