Hi Linda,
You have so many different options for accommodations. It really depends on your budget as to whether you want to stay in a Value, Moderate or Deluxe Resort. You can do 2 rooms in any of those and request they they be adjoining (near each other). Browse this link
here and see which resorts fit in your price range.
If Deluxe is an option, I highly recommend the
Yacht and Beach Club or the
Wilderness Lodge.
For payment options, you can make a $200 deposit per room when booked as part of a Magic Your Way Package (which includes tickets). Once you do that, you can make payments whenever it is convenient for you as long as the package is paid in full at least 45 days prior to your arrival.
Once you narrow down your options based on what works for your budget, I'd be happy to give you feedback about specific resorts. Simply send me a follow-up question.
Wishing you a wonderful vacation,
Kaylene
