@Marian - I really don’t know what his preference is. It doesn’t really matter at this point since we are going to have to farm him out if he comes. An air mattress was never an alternative - no room. We were uncertain at one point last year if our friends were going to depart before ds arrived. Dh said we could put ds on the couch. I reeled at this idea and said, “No way,” even though it would have only been for one night. The timing worked out perfectly with our friends last year, but I would have insisted we get ds a place somewhere else - even for one night. It’s one thing to make a 12-year-old (or even a college kid) sleep on a couch. I’m not doing that to my young adult ds.
