Justifying the 1BR over the Studio, even for 2 people, is easy: jetted tub, washer/dryer, full kitchen, king bed and the living room.
A DVC studio is "just a hotel room" in my eyes ... w/out daily housekeeping. Why bother??
Fortunately for us we don't need the kitchen and the living room...

Washer and Dryer would be nice and the jetted tub is what I want most but for more than double the points I can do without.
The kitchenette is more than enough for us. All we do cooking wise during vacation is cereal and cold sandwiches. I love to eat out and DH is easy to please (turkey deli and chips and he's happy ... ).
Now with kids that'll be different. I wouldn't want to do less than a 1br.
But we haven't been blessed with any yet, so it's a studio for us right now
