At Coastermania I have always stayed at the Breakers, first in the Bon Air section, then more recently the Tower. It's REALLY convenient because after 12am or 1am ERT on Magnum, it's just a few steps away! However, I wouldn't be a it surprised if it's booked up this close to June.
Last August I also tried the Breakers Express and it's nice too.
If there's a room, and you don't mind spending a few extra bucks, go for the Breakers. Besides, it's a very historic part of CP, and every CP nut should try it once.
