Are you trying to get a two bedroom for one family for the extra beds, or do you have more adults traveling with you.
There is no guarentee with a request that you'll end up with the connecting studio - and I think its a pretty high risk that you won't end up with the connecting studio. So if your "second bedroom" occupants are adults that could stay in a studio, its worth a shot. If your second bedroom occupants are your children and you are just thinking that with this great rate in your hand you might as well have them sleep somewhere other than the living room - I think your chances of ending up with a studio that doesn't connect are really high - in which case you'll have spent money you can't really convienently get anything for.
