I would have thought it would be more cost effective to move you to another hotel. Hong Kong airport is mainly operating normally and most guests would only stay a few nights so there can‘t be many left. The ones that are would have a long journey to get food and supplies so it wouldn’t be much fun. Couple that with the cost of continuing to staff the hotels and run transportation to the resort etc and its odd to me that Disney haven’t closed the entire resort save for skeleton maintenance staff to keep things ticking over.
ironically the resorts location would be perfect for an isolation camp but i cant see the HK government doing this even with their current issues with Disney management and the second park site
