I honestly never thought of this! How interesting. My ds was never the type to get into stuff, but my dd is- big time! I guess I'll have to baby proof the room on our upcoming trip.
When our grandkids were babies, we always took a stroller sunshade and used it a lot. Their little legs got red really fast if not protected, even with sunscreen.
We put sunscreen on our son's legs when the UV index would hit 3. And then we were back in the hotel each afternoon. So I think that helped a lot. (If we had stayed, we would have reapplied often.) He didn't burn at all.
Honestly, my baby proofing list for 2 two year olds is nothing (except a leash, i'd rather die than not have the leash for disneyland). They are Those Kids and can climb anything I can at 5''2 but are more careless about. The painters tape is genius, especially for the phone because that would super be happening.
