Depending on some people's needs or priorities in accomodations, it might be a better choice since it is not Disney run or owned or managed.
I absolutely agree and I didn't state one choice was better than another. I'm just stating, again, that's it's not an actual Disney resort. So if someone is looking to book a room at All Stars or CBR or an official Disney resort, that cannot be booked through Costco. That is my whole point. That if you want to book an OFFICIAL DISNEY RESORT, it cannot be booked through Costco.
If you want to book Swan and Dolphin, B Resort, Hilton Bonnet Creek, etc. those CAN be booked through Costco for great deals.
