Wanting to take my kids and grandson to Disney Christmas of 2019, I have over 1.5 million points. We'll need 3 rooms for 6 nights each. A couple of questions, can I (or should I) use all points to book multiple rooms at the Swan or Dolphin and how soon would you book? I know I have to wait until its 50 weeks out - but would you wait longer? Trying to figure out my best options - any advice is welcomed!
