We are only a family of 4 but we started doing 2 rooms at resorts years ago. Our favorite is POFQ and we request connecting rooms. It works out great to have 4 beds, 2 bathrooms, 2 TVs, 2 fridges, and extra space in general. We enjoy POFQ as it's a compact resort, has only one bus stop, great QS food, quaint atmosphere and boats to DS.
That being said, next year we are doing a split stay with 2 rooms at each resort, CBR then BC.
So much depends on your budget, park touring style, time of year, if you will have a car, and whether a pool is important. A little extra info and I think you will get more informative responses.
