From the description, I think the post above is referring to the Renaissance Resort, not the Residence Inn.
The Residence Inn is pretty much like other Residence Inn's, except much, much larger. They have a large breakfast area (complimentary), but it can get crowded.
Also, there are several Residence Inn's in Orlando.
The one by Seaworld is 'Residence Inn Seaworld/International Center', and is on Westwood Dr. I assume this is the one you will be at.
The 'Residence Inn Orlando International Drive' is in the I-drive corridor area, on Canada Ave.
