I base it off of what we are going for, for that particular trip. To me the beauty of Disney is each trip can be totally different. Our last trip, I was pregnant so we didn't want to have tons of park time. We did 7 days at WL, and planned on being at the pool till 2-3pm almost every day, and wanted to enjoy the more upscale Disney dining. Being close to Artist Point, Cali Grill, Narcossee's was what we were going for. I could get a good deal on WL so we went with that. It was the most relaxing Dis trip we've ever done.
Our next trip will be a group of over 20 ppl. For that we are doing FW cabins, because its so great for groups, yet with all the little ones its still close to MK.
Ideally we are MK and Epcot fans so being on or near the monorail is top priority. However we also love Beach Club because we really enjoy walking to Epcot and the vibe of Stormalong Bay.
For us, give us Deluxe over any! But I'll never pay full price.
