Yes, but again an oversimplification.But with HRC, even if two units in different locations are assigned the same amount of points, don't you still have to hope that the week you want was traded or given up by another owner if all the prime intervals have been bought?
With many timeshare groups, if you want a certain week every year you must be on the phone/computer at an exact time/day months in advance and then 'hope all goes well. And forget multiple rooms.
With HRC, you can buy that week, + for HRC. - for HRC is that it is a fixed week, and if you want the week before/after, you are in the same group with everyone else trying to reserve it.
With Welk, I believe it is the same as most timeshare groups - Be on the phone/computer far in advance to get the week you want if it is a high demand location. The main difference here is how many Welk locations have a huge specific season/demand. Therefore, it may be quite easy for you to get whatever unit you want, wherever you want. I don't think Branson or San Diego have a season where people are clamoring for specific dates/rooms.
Same with Hyatt in Sedona and a few other places, reservations are pretty easy. Key West in J,F,M is even easy - (just not Sunset Harbor)
