Dean- Just so there's no confusion, for the unrestricted July week make sure you do an initial trade between now and May, at least 60 days before the expiration date of the July week. Reserve a week for July 2023, as close to the expiration date as possible, and purchase the Eplus option. At least 60 days before the expiration date, retrade using your first Eplus to a July 2024 week, again as far out in July as you can. That leaves you 2 more potential retrades through July of 2024. If you can't use it before then, then call in May of 2024, at least 60 days before the trade expires, and request a cancellation replacement week, which will effectively extend your initial deposit to May of 2025.
As for the restricted week- maybe
@dioxide45 can answer this- but if an exchange was made within 59 days of the July 2023 expiration date (but I'd do it over 30 days so as not to incur a further restriction), wouldn't the Eplus extend the expiration date the full year (also to July of 2024), but you could only reserve something where check-in was within 59 days? I might be wrong, but I thought the restricted last minute exchanges had a limitation on how close to check-in reservations could be made (either within 59 days or less than 30 days) but the expiration dates were not affected. I know that's the way it is with the original Flexchange deposit, but not sure with an Eplus add on.
