I'm sure you'll have no problem. We booked a 2 bedroom at OKW and a studio at BWV for July at the 7 month window , no problem at all. Then last week we found out the family we intended to share our 2 bedroom with can't go. We called MS and easily switched to a 1 bdr at OKW and a 1 bdr at VWL, again no problem and this is only 2 months out.
