You truly must have some of the worst
DVC luck, we have never experienced any of this in our over 22 years of owning. We rent timeshares all over the country and much of what you are upset about is standard for time shares. If I don't like the TP, I bring my own. Never have I gotten a robe at another timeshare. Never had dishes not clean at DVC. Never had houskeeping at all during the entire stay at other timeshares. I don't find the views sad, Do all the resorts have great views, no, but they offer more like location. Most have really good views. The only exception is BCV and it makes up for those views with other amenties. As to the mattresses, we liked it so much we bought one like it. Linens are similar to industry standard.
I really think you are expecting a hotel experience in a timeshare and that is not going to happen. Our room has never been entered as we keep the lock on every time we are in the room.
