When you are assigned a week from your home timeshare, you can deposit it with (II). The trade is good in II's bank for two years. Last year I did not use my week to go anywhere on vacation so I could save it and take a two week vacation this year. Recently, I called II (paying the extra $20 to talk to a real human in order to avoid mistakes!) and put in my request for one week in Molokai and the following week in . In relatively short order, my trade was confirmed for the week in Maui!.
Then, I got to thinking, what if they trade doesn't go thru for the week in Molokai? So, I called II to make sure they used my older (2011) week, the one that expires 2012 for the trade and not the newer one that expires in 2013". Sure enough, they used the newer week for the trade!. In other words, if the trade for Molokai did not go thru I would be cheated out of one "banked" year.. When I got no satisfaction from the first guy, I asked to speak to a supervisor (probably his peer sitting at the next desk)". She gave me the same song and dance ("we have no control how the computer makes the trade" BS), so I asked why they could just go in the computer and switched the two weeks, a simple |. Can't be done, she claimed;. I told her to cancel my request for Molokai". She did extend my older week (to one that expires this year) for 4 more months, which really doesn't help me or solve the problem.
I have been an II member for 20 years and as the mandatory membership fees AND trade fees have gone up, the service has gone down. Be extra careful if your timeshare only allows you to trade thru II.
