My 5 upgrades that have happened since '93:
1. Once cause of over booking at VWL:
Booked a studio at VWL, when we tried to check-in, we had been upgraded to a WL 2 bedroom lake view suite. Called some family members to come and join us for an unexpected vacation.
2. Once cause of problem with check-in at AKL:
Booked a standard view studio at AKL-Jambo, checked-in, given a room key as the room was supposed to be ready, went to the room, and found suitcases and purse in the room along with the room not being made up. Went back to the front desk, they gave us an on-the-spot upgrade to a savanna view room in another part of the resort plus four free breakfasts.
3.
DCL
Reserved an inside stateroom on DVC points but were upgraded to an ocean view room. We did not find out about the upgrade until we got to the room, what a surprise that was. When our luggage arrived it still had the old room number's tags on them.
4. AKL-Jambo
Booked a standard view room at 5 days out due to a last minute change in home plans. Given a Savanna View room.
5. AKL-Jambo
Got another upgrade in Aug ‘16. Reserved a standard studio, on Sunday before leaving the house checked status of points, made a reservation, etc; found that I had more points in my account than I should have and points in Holding that should not of been there. On the way from home to AKL, I called MS, asked for a status of my points, and they stated they saw the same thing on their system.
After being put on hold, MS came back with an explanation, stating that we had been upgraded from a standard to a full-savanna view room. The points in holding are there for the backroom process of the upgrade. Checked my points on Sunday evening and everything is correct. The room we were given was 5268 with no pen in the view except across the savanna.
