can't tell if you are 5 or 7?
with 5 - you can get a room at Polyn, cr - these are big - you would get 2 queen beds and generally a twin bed (day bed)
with 7 - you do need a 2-bedroom - the ones at BLT and AKV - are different they have an extra chair bed and an extra bathroom - so 3 bathrooms in a 2-bedroom - vs a 2 bathrooms - now OKW has the extra chair but not the extra bathroom.
you get a king bed, queen sleeper sofa, chair bed and generally 2 - queen beds in the second bedroom - if you get a dedicated. the lock out is what goofy4tink describes so well.
several
DVC member don't use the kitchen at all. Now I have food allergies and while Disney does an excellent job with food allergies - don't like to waste hours in their restaurants. So cooking in my studio or villa is great for me.
BWV has no dedicated at all - so if would be a lock out
BCV is strange - it has 25 true dedicated - but most of its dedicated is queen bed and double sleeper sofa in the 2nd bedroom.
BLT is the most expensive - that is location - you can walk to MK and monorail to Epcot
BWV and BCV you can walk or boat to Epcot and Studios.
the others are not close enough to walk to theme parks.
