I have to agree that it can be hard to go back to moderates once you've stayed either at the deluxes or the DVCs. I enjoyed the moderates when I was younger and when that was all I felt like I could comfortably afford. After trying various deluxes, I used to try to stretch our dollars by doing a couple of nights in a moderate, then a few nights at the deluxe of our choice. I haven't been able to bring myself even to do that for the last decade or so. We discovered Club level, and there was no going back. When we started looking at
DVC, we actually worried most about losing the ability to book Club level easily. (Yes, I know it is available at AKV, but there are few Club level rooms and they're tough to get... and only half have Savannah view.)
I have to say, I haven't missed Club level toooo much. We bring our own alcohol and snacks, and we leave them in the room so we can treat the room like our own concierge lounge. I was worried that we wouldn't have IPO to get our ADRs for us, but I've had really good luck, particularly now that the online option is available. The extra space in the one and two bedrooms really spoils you quickly, so we don't even miss the GF the way we expected to. (Now, if they would just build a GFV, particularly if they let DVC members have a Club level option, we'd be thrilled.)
We've been DVC members for a year. We've added on once. (We knew we wanted points at at least two resorts - we bought AKV direct and we bought BWV resale.) We've been extremely happy with our membership so far. We may add on more points once we see how we use our membership once the newness wears off. We're big fans of other types of vacations, particularly cruises and exotic destinations, and while DVC in theory can be used towards these types of trips, it really doesn't seem like a great use of points. Right now, we want to make sure we have enough points to cover all our WDW trips; no more, no less.
