Yes if you buy into Marriott properties you have one of the most flexibletimeshares. In over 20 yrs of ownership I have never needed or evenwanted to use other agencies (such as Interval International) - but havestayed in Hawaii, Virginia, San Diego , and more. They are very helpfulin getting you to were you would like.

All Marriott owners - whether they own points or legacy weeks - canexchange through Interval International to access Marriott ornon-Marriott properties worldwide.

Though this may be the intention, it is not true that all Marriottresorts have been removed from II. We are booked in the MarriottWilliamsburg this April. Other Marriott properties are still availablethrough II but not the best ones.

The statement that in Jan 2021 Marriott will remove all resorts in II &no longer able to exchange through II is completely false. There isnothing from Marriott or MVC about this..I spoke to a IntervalInternational rep and they have heard nothing about this. There are lotsof Marriott owners that have weeks that they bought resale & tradethrough II. You can buy a resale and add it to II. You can then use theresort, trade it through II or rent it.
