I don't think that the producers would enjoy having to defend kicking a survivor off the island for seeking shelter under a boat. But it would a tight (albeit warmer) fit for all of them at once.

Speaking of which, body heat? Heat of the hive? OK, I'm picturing a heaped up snore-fest of nose whistles. I do not think the producers or editors would turn down that scene.

And considering that normally they would welcome and even encourage a cross breeze in what would be normally hot tropical weather (believe me, that really helps at night with no A/C), shelter walls are actually a be a bad idea. Except of course, when the monsoons hit. You build the platform to get you off the ground and a roof to block the sun. Until they get tarps, and unless they have experience with them, those palm frond roofs probably aren't rainproof.

Walls? Why would you erect walls? Camera rules probably aren't the reason there are no walls. A sweat box isn't what you would be aiming for.
