Welcome to the DIS, mellormousee!
Just one more thing to take into consideration:
The dining plan is LOTS of food. If you think it might be too much, 2 studios would allow you to only pay for the dining plan for 1 room. You then could share credits, if you chose. That would allow you to eat at non-Disney places a couple of times also, if you wished.
This may be of no interest at all to you, but just thought I would mention it.
