If the person who is buying and has a II account and only plans to stay at their home resort, and is somewhat flexable as to the week/chech in day that they can go in the low season, IT WOULD BE BETTER TO NOT BUY.
If they are buying a silver MSE, can travel on short notice, and are open to many travel locations, and want to stay in Marriotts, a resale MSE week could work well! Low up-front cost (could be close to ZERO), $850 in maint fees, $75 to lock-off, $99 per trade fee to a Marriott, Marriott internal exchange priority $0 = $1123 for two weeks in a Marriott 2 bedroom or larger, in high season, anywhere in the world is possible! It could work out for some people.
A Branson week would cost even less. I am sure that there are many low season Marriott owners who are VERY happy, and are NOT nuts!
