I have a ton of experience trading and trying to trade to MGO for week 25 & 26 +/- 27 but mostly week 26. I routinely have 1 or more Marriott to Marriott exchange requests going done 1 year or more in advance, usually more than 1 request and usually before 14 months out. I'm using traditional MVC traders, mostly Willow Ridge though I've used Legend's Edge, GV & HL as well always the best TDI for each resort. Other than 2020, when I got 5 units on exchange, I've gotten 1 most years and none a couple of years. I seem to recall one year I may have gotten 2. One of these was on a priority search because II made a mistake. I generally get them 4-6 months out but sometimes under 60 days. I think one can expect a similar experience weeks 24-30 though just having the option of more weeks will increase the chances of success a fair amount. Being open to August and early June will make it much easier. Still, there's no reason not to try though I would not put ONLY MGO unless I was prepared not to match. For us we have other units the same resort and week and are either looking for additional volume or to substitute the exchange for a direct reservation and either rent it or more likely, cancel and use the points later.
