I was also going to say that. I was trying to email MS through the website last night and couldn’t click the “done” button. I chatted with MS and they told me to clear the browser history and/or use an incognito browser window. The issue was the hyphen in my last name.
You may just be suffering a normal problem if you are seeking certain high demand rooms. For example, for that Dec time of year BWV resort and boardwalk view studios (and 2BRs), and AKV value studios (and 2BRs), often fill for any given start date at 11-months out within a nano-second past 8 a.m. and many making the attempt just get an error message.
Yes, you can chagne room size, book into the same room size but different view, or change dates---all of which can be done independently.
I have had it happen in the past. My recommendation is :
First week of Dec is actually the highest DVC room demand week of the year at WDW, second week is third highest. (Christmas week is second highest.) The first two weeks have long been in that position. It was generally caused by those first two weeks having lower point costs than other times in the fall (before 2021 the first two weeks of Dec actually had the lowest per night point costs of the year), the ability to see lots of Christmas things at the time but not having the parks overcrowded, and the fact that the annual members' meeting usually took place during that time.
They would be inundated with complaints. The DVC and even Disney website’s reliability is awful. It is the worst site I have ever used, by far. Management is ok with it because they don’t want to spend money to make it work properly.
