Well, first of all, welcome to the forums.
Second of all, and please don't take offense, but I think most people posting in this section of the forum are DVC members and therefore wouldn't have to trade anything in to get a DVC unit, you know what I mean?
DVC works different from some other timeshare companies. Whereas some timeshare companies sell you a specific percentage of a specific property (or specific resort area), DVC members are assigned "points" that can be used in any of the DVC resorts at any time. You are assigned a "home" resort (in my case, Saratoga Springs) but I can book at any of the other resorts. The only difference is I can book at Saratoga 11 months in advance, and the other resorts I have to wait for a 7-month window. The amount of points you use depends on the resort, the size of the villa (studio, 1BR, 2BR and "Grand villas" that sleep 12), and the time of the year.
Alternately, DVC members can use their points for vacations elsewhere, primarily but not exclusively through Interval. We jump on the DVC website, and there's a link to the resorts available to us through Interval. We would call up DVC, tell them where we'd like to go, the hotel(s) in that locale we'd like to try. The DVC rep will tell us if it's available, how many of our DVC points it would take to stay there, and if we want it, the rep takes care of the rest. It's not really a "trade" scenario, per se, our decisions to stay outside of WDW are just based on availability. Or maybe it's because Interval always has plenty of people who want to stay at WDW, so it seems like we have better chances of booking outside resorts, so it doesn't seem like an issue.
So basically, the only way you're probably going to get a response is if someone here is a DVC member who wants to stay in Maine and willing to trade, but since we can do the exact same thing through DVC and not risk a deal with someone we don't know (again, no offense), probably not going to happen.
And finally, you don't have to necessarily post the same question twice. You can always just bump your original question up to the top of the list if you're afraid it's going to get lost. Of course, since your first post was already at the top of the list, it's safe to assume that anyone who saw your post didn't know the answer to your question. And this isn't as highly trafficked a subforum as the other categories. Patience...
Here's pertinent info from DVC's website...
Interval International Exchanges
Reserved Disney Vacation Club Resort accommodations can be exchanged for Interval International accommodations. Exchange weeks become available when owners at a resort in the Interval International program give up their week for exchange.
When you contact Member Services, a search will be conducted for an instant match.
If an instant match is found, your Vacation Advisor will confirm your exchange.
If an instant match is not found, you may request to have the system continue to search until a suitable match is found.
Your Vacation Advisor will contact you when a match has been found, and you will have two business days to return the phone call or your search will be cancelled.
Depositing Accommodations for a Future Exchange
With Interval International, you have the option of first depositing your reserved Disney Vacation Club Resort accommodations into the exchange system, then deciding later where and when you'd like to travel. However, once deposited, Disney Vacation Club Resort accommodations cannot be withdrawn.
If you deposit accommodations within 60 days of the start date of your deposited week, this is considered a "late deposit." In this case, an exchange may be confirmed only by calling Member Services 59 days or less from your requested check-in date.
Exchange Guidelines
Exchanges can be booked on a weekly basis (generally weekend to weekend).
A non-refundable $75 exchange fee is required when an instant match is confirmed or when a system search is initiated.
