It may vary based on how busy the resort is any give week. The key is to make sure the requests are in before the rooms are assigned. Picking a Floor and a building may not result in a perfect match. What room category did you book since many of the Samoa rooms are Water view?
Everyone seems to ask for the Samoa building on the hotel side since it is between the 2 pool. If you don't get your building choice or a balcony assigned in
MDE then stop by the Front desk and see if they have any rooms that may better match your 2 requests.
Only the DVC buildings have balconies on the 2nd floor. That's why the picked them for DVC conversion.
