Yes and no...
You can book just a one bedroom for yourself and have the request to connect to the studio that checked in the day before (make sure the request is noted on both reservations).
You can book the studio for one night and a 2bedroom lockoff for the rest of the stay with comments, again, on both reservations stating that it is a continuing reservation and you would like to stay in the same room for the entire time.
However Member Services can not "link", in the correct term of the word the reservations. Linking a reservation means that you check in one time and even though you may have more than one reservation you do not have to come back to the desk as the computer will automatically check you out and back in. A true "link" can only be to the same room type.
So you can go with either option booking the studio for the entire stay and booking a seperate one bedroom for the entire stay and asking them to be connected for a 2 bedroom or booking the studio for one night and the 2 bedroom lockoff for the rest of the stay and requesting that the studio be abel to stay in the same room the entire time.
