Hello and welcome to planDisney, Rita!
You have asked a great question, and I am personally a fan of the larger spaces when we visit
Walt Disney World Resort.
A two-bedroom consists of two bedrooms in the same unit and space. In comparison, a two-bedroom lock-off consists of a one-bedroom and a
deluxe studio separated by a door. I like to think of it as having two joining rooms that can be closed off if need be, especially if you happen to travel with a separate family (for example). Either way, you can not go wrong because they consist of a full kitchen, two full bathrooms, and a washer and dryer, among other amenities.
Please return should you have additional questions; we are here to help.
Have a magical stay!
Raquel
