Steven Tyler -- Livin' On The Edge Of A Lake ... In A $10k A Night Pad!!! (PHOTOS)

Steven Tyler hit up Walt Disney World over Easter weekend and while he didn't crash at Cinderella's Castle, the place where he did stay looked like its own mini Magic Kingdom.

TMZ has learned ... Airbnb hooked up the Aerosmith frontman in a $10k a night lake house in Windermere, about 20 minutes outside Orlando. In other words ... Steven paid zilch to stay there.

We're told he came with his family and there was more than enough room for everyone because the place is huge.

The 4-bedroom home has its own dock on Lake Butler for anyone that gets tired of swimming in the pad's lagoon-like pool.

No doubt Steven slept like a baby after riding the Aerosmith Rock 'n' Roller Coaster ... yep, that's a ride there.
