I absolutely adore DLP. But I haven't been to TDL yet (next month!).
After careful consideration I want both...
But if I could only pick 1 I would pick TDL. Simply because OLC have proven themselves to be above and beyond in keeping the parks up to date and current with shows and merchandising, events, etc.
I think I would really really be ecstatic if they would open a dvc resort there.
Currently room using points there is 56pts/night and above. If they open a resort there with a third of the points requirement I might be putting them on our vacation rotation of some sort (WDW, DL, TDL every 3 or 4 years). That would be absolutely wonderful.
The first and last time we went to DLP they still have not completed their Studios. The place was still pretty empty. But if they complete the whole park it'll probably be pretty amazing.
