'Honey Boo Boo' Family -- We Were Sweating Like Pigs ... In Our L.A. Hotel Room

Honey Boo Boo and her family may look like they're enjoying the sun while sitting poolside in L.A. ... but TMZ has learned it's actually been more like a vacation FROM HELL!

Sources close to the family tell us ... when the Shannon clan got to their hotel room Tuesday night, the AC was busted -- so the hotel gave them some fans to cool off for the night.

Even worse for Mama June, Sugar Bear and the fam -- their toilet wouldn't flush.

When they switched rooms Wednesday morn, the toilet was working ... but the AC was still kaput. Which is why the Shannon clan hit the pool to cool off -- then pulled up stakes and switched hotels.
