I'm happy to answer anything I can. I'm an owner there.
Like Denise said, there are reviews and pictures and other details in the TUG marketplace. There's also a section wherein TUG members can input details about sales - a price history.
I got my ownership on eBay for about $50. It's a two bedroom, ocean view unit. It's an every other year ownership. The MF increased when Diamond took over, but they also made clear improvements and seem to continue to make improvements. My ownership is not through DRI. The way I make my reservation has changed over the years too. Currently it's a pretty simply process online. I easily get the week I want

I really like the place and enjoy it but some people would not like it. It's not a Marriott.
It's very close to train tracks, which annoy some people. My son LOVES it and I think it's fun too. My family can sleep through anything so it doesn't annoy us. We like the pool a lot. There's nothing too special about it but it's a nice temperature and there are usually friendly people there using it - kids to play with etc. The nearby beach is nice (I strongly recommend using the north part of Doheny beach where the snackbar is and the volley ball courts etc, though, not the south part that is directly across from the resort).
By the way, it's looking like they're replacing that pedestrian bridge to make it ADA accessible which will be a HUGE improvement. That means an elevator! It will make street parking more of a realistic option and it will allow people with disabilities a safe way to get to the beach without having to get in a car. For me, the exciting part is that we always use bikes when we go there and this will make getting the bike to the beach easier and safer. I think that whole section is going to improve with bike paths and better sidewalks etc. It's going to look more like Dana Point and San Clemente.
