I've gotten some great trades in the recent past:
I got week 51 in a 1 bedroom ocean front unit at Marriott Kauai Beach Club using a Grand Chateau studio.
@marmite got me a week 52 (from 2022 to 2023) at Marriott Waiohai a few weeks before we were scheduled to arrive with a 1 bedroom at Grand Chateau. It was great because I was planning on staying at the Grand Hyatt (so saved a bundle) and had enough room for my father in law.
I'm not sure how, but I got a couple of weeks at HGVC Kingsland for 39,500 RCI points per week for the first and second week of July. I had an ongoing search, and when I checked the number of points, I was shocked and booked it immediately.
It's not the hardest trade to get (and I specifically chose a large resort to make it work), but I've gotten 5 trades for the week of memorial day at Newport Coast Village for a family reunion. All 4 of my siblings and I will have our own units.
It wasn't an Interval exchange, but I had trouble sleeping in the middle of the night while I was at Kingsland. On a whim, I logged into the Hyatt system and found not 1 but 2 units at the Hyatt Siesta Key for Week 52. It was awesome, we brought family for the second unit and had a fantastic time at our favorite resort.
