This post on the Royal Resorts News Ask Joanna page offers some clarification:
The all-inclusive packages will be optional for Royal Resorts members regardless of how they are staying at the resort, whether it is in their own villa or in a rental or exchanged unit. Family and friends staying as guests of a member in their unit(s) will have optional access to all packages.
With regard to your question about exchanging or renting additional space for your guests, I can clarify that if the rental, exchange or guest certificate reservation is in your name as a Royal Resorts member then access to the all-inclusive packages would be optional for the occupants. If the reservation is in the name of a non-member the all-inclusive package would be mandatory.
I hope that this helps answer your question. Please let me know if you have additional concerns[/B].
For what it's worth, we need to provide objective feedback to RR management about the exchange policy.
