I've heard a lot of good things about Samoa. It's close to both pools and an easy walk to the GCH for access to the monorail. Make sure you also request either the first or third floor if you want either a patio or balcony. Most buildings have fake balconies on the second floor. But depending on when you arrive there could be construction on the Oasis (East) pool, so you might want to request facing the Lava pool.
Here are some tips from AllEars.net

"Faxes are preferred to phone calls because it allows the room assigner to block requests in their own time. Phone calls can come at bad times and lead to a cast member making a notation on your reservation or on a piece of scrap paper and not actually blocking a room. The fax actually gets put in a file and rotated between the room assigners until you check in. If for some reason the room that was blocked for you gets moved, the next room assigner in rotation should catch it but remember that it is always possible that your preassigned room can be changed for many reasons right up until the moment you check-in. Requests should be faxed directly to the resort and marked "Attention: Room Assigner".
No requests should be sent until 4 days prior to actual check-in. The resorts do not get to download the reservations from the DRC computers until 10 days before your arrival and the room assigners generally block your rooms 3 days before. If you fax a request to a resort before they have the reservation in their computers and are ready to assign it, they will file it in a special "pass" folder. That folder should be checked daily to pull out faxes that came in early but there is always the chance yours could be missed. The best way to avoid getting in the Pass folder is to not send in your request until 4 days before.
Faxing after 4 pm is usually best only because the morning Room Assigner is usually bogged down with checkouts and the evening Room Assigner is usually dealing with check-ins until 4 pm. Honestly though, if you are faxing it doesn't matter when you send it. If they are busy they will file it and the evening Room Assigner will get to it when they start blocking request"-- Jack Marshall Allears.net
