When you travel, how do you handle it when the sleeping situation is less than ideal? At my MIL's, we usually sleep in a double bed, but the mattress is so soft I don't feel comfortable with DS sleeping in between us like he does at home. And at my parents house, the mattress is great but the headboard has wide slats that I'm afraid he could get his head stuck in between. Other than having us sleep on the floor (not very comfortable) I'm not sure what else to do. We have a pack and play that he naps in sometimes, but I'm not so sure he'd be very happy sleeping in it all night.
