In a lock-off you get the wet bar area and extra fridge in the studio plus you can close the connetcing door between the 1 bdrm and stusio for some privacy.
We have only made 2 ressies for 2 bdrms in the past and each time it has specifically stated dedicated on the confirmation. In each case that's what we got.
