Well, I don't think I would buy any more DVC points there, even if I could afford to.
The one and only time I stayed at the Poly I just found it way too busy with too many people hanging around waiting for the restaurants or crowding out the pool. I really wanted to enjoy it but it was not relaxing at all and I won't be back
All the extra DVC rooms will make it even more hectic around there and I seriously doubt that the monorail will be able to cope, especially with all the extra people at the GF DVC. Someone better be looking at the bigger picture with pools and transport too and not just rubbing their hands with glee waiting for the money to come rushing in.
