Depends on how one wants to count 'a trip'.
We'll go to Florida at a minimum of a couple of times a year, but will stay anywhere from 6 to 10 weeks at a time.
During that time, we might go to Disney for a awhile, then go somewhere else in Florida, then somewhere else, and eventually back to Disney again once or twice (or thrice) during the same 'trip', before eventually going home to Indiana. So is that one Disney trip, or two, or three, or six?
Or saying it another way, in a year's time, we'll spend about 30+ nights total at or near Disney, a combination of DVC, on-site hotels, and off-site (non DVC timeshares or hotels). Ranging from 1 to 7 nights at a time.
We do a lot of combined trips with my brother. Sometimes I'll get the DVC 2-B/R and he stays with us, and other times he'll get a 2-B/R and we'll stay with him.
