I didn't travel with
AbD, but I did a vacation package. There are pros and cons to doing that vs a normal hotel reservation. Pros are that you get a lot of skip the line passes, everything can be booked at once rather than through the app on the day of, and hotel room availability is normally better. Cons are that it doesn't save you any money and the maximum length is 3 days/2 nights, so you'll still need to book additional room nights. I thought it was worth it because I only wanted 3 park days anyway but also wanted to maximize my time with the premier access.
Here's a link to a previous post where I rambled for a minute about the parks:
