Toddler air mattress. Our 3 year old rolls way too much to go in a regular bed while traveling. The air matrrsss is perfect. Low to the ground but with bumpers on each side so he can't roll off.

Shrunks travel bed. Easy to set up, comes w a pump, has lasted us 3 years already. Fits in a suitcase easily for air travel too.

You and your kid are/were lucky. I have a 3.5 year old who will absolutely not sleep anywhere and if he slept in the same room as us would be up about 100 times a night. We put him in a separate room with a travel toddler bed and use a video monitor. Our parents have houses similar to the OPs...we clear everything out of the room that's not heavy furniture.
