Sleeping in the tent doesn't heal the party if there are clerics in the party. Sleeping on the ground does (as usual), but if you are using provisions, this uses one up. It would be nice if the tent also left the party fully refreshed after a night's rest.

The tent was added later to lower the chances of BG2 dreams, which could potentially lock the party in that area forever (because the dream uses storepartylocations just as teleporting to that area does), and it's just how script rest works. The only way would be creating a spell that is always cast on the team whenever they rest, but that would make party clerics less useful, and it would feel even more like a cheat. Sorry, that's how it is, and I would rather keep it as it is. This is already a huge advantage and may possibly be abused, that's also why I don't want to make it an even more powerful place / feature.

May I ask please how I could go about getting My Very Own Hideout in BG2? I was looking at the files in \override in my BGEE install but got more confused  

Ahh....I just realized EET was probably the solution.
