I believe you already have an II account from your other Timeshares. Just log into your account and select the option to add a timeshare. You can also do it over the phone. You will provide the details. iI will take about 24 to 48 hrs to confirm the details and will let you know via email when it is confirmed. In order to deposit in II to begin an actual exchange, you have to pay the maintenance fee of the year you are trying to use before the resort will release the unit to II. For the lock off process, you will select lock off when trying to add the unit to your account. Once confirmed, it will show up as lockoff in II. You will then have the option of depositing the whole unit for exchange or just one side. If you have EOY, you will also get to choose a deposit year in II. Pretty clear on II. There is just one step I need to confirm. That is if I need to call the resort and make a reservation for that week before II can pull it. I will find out soon enough as I am about to pay my MF for 2 years to be able to deposit 2026 units to II for exchange.
