How about a mattress topper? Order from
amazon and deliver to the hotel you can find one for $50 . My son uses this in his dorm room and nothing is more uncomfortable than those beds. You could just leave it behind afterwards and would still be able to stay where you want to stay. I personally have slept on the pull outs multiple times and honestly I do not find it that bad but that’s just my opinion. I certainly could sleep. My oldest has also slept on it and really did not complain he’s 6 feet tall. I think it just depends on the person honestly.
