I believe they are in different wings or buildings. The premier rooms are in either the main building or the the new section by the pool. The others are in either the east, south or west wings.... Premier is much better in my opinion.
There are some Premier rooms in the new building by the main pool. There are also some in the Main building. If you want a newer room, you can ask for the new building or building 2 when you arrive, but there are no garauntees. All the rooms otherwise have been renovated.
I'm ready to book my vacation for October also and I'm also trying to decide which ocean view type to choose. Is there difference in views? If premier is better, why? Is it the view, the location, the room quality? From what I read here, the only difference in the rooms is the location? If so, what are the better locations at the resort. I haven't stayed at CTI before, but sure am looking forward to it!
