All: Thanks for judging me so hardcore here. What a welcoming community this is.
The truth of the matter is that I received 5 emails about the reservation. One person offered $650 via email 3 hours after the post, when I had already received other offers for the $450 (however, I had not replied to anyone or even seen the emails yet). I then thought I was being a gentleman by offering the first person who emailed me the opportunity to match that $650 offer. Apparently, that is not the case.
I have the reservation in hand, and would never steer someone to a reservation that is not real or confirmed.
I acquired 9 timeshares in 2021-2022 from this forum thinking that it could be a way to pay for my family to go on vacation by renting out what I could not use. That was completely wrong. Since then, I've had a child, 2 miscarriages, and my income has fallen by over half while I have to work 20+ more hours a week than I did then. I'm losing over $10,000 a year on this failed business. The maintenance fee for this reservation was over $1,100. You'd take the extra $200 if someone offered it to you out of the blue, too.
