Have you looked at exchanging it through other exchange companies? You might consider looking at SFX. I think it would be considered high demand for them. There are still exchange fees, but you can exchange to a lot of other places that won't have the resort fee if you feel like you will still be taking one week vacations. For example, I just paid $149. to exchange to a one bedroom new hotel in Anaheim. No additional fees.
I cannot remember if Coronado Beach Resort trades in RCI or II, but that week would be considered high demand in either of those. You'd have to pay a yearly membership fee and the exchange fee. You'd have access to a lot of locations and many of those won't have a resort fee.
It sounds like you aren't in any type of hurry, so you can list with their resale department. Call member services and ask about it. I cannot remember what it's called, but they have another company that resells some of their properties and I believe that Coronado is one of them. They list at ridiculously high prices, but people who want to buy there and have never heard of Tug and don't understand the resale market will probably buy from them. When I wanted to purchased Villa L'auberge, they had some for sale and I think the cheapest one was around $7K. I found the exact unit that I wanted on Ebay for $53. and bought it on Ebay instead. That's just to give you an example of how high they list their resales. I also never saw any units sell from them, but if you aren't in a hurry it might work out for you to keep exchanging your week while you wait for it to sell through them.
Another option is to rent it out. If you rent it out yourself (don't use GPX rental service), you should be able to cover your costs and make a few hundred bucks on top of it.
