Hi Ken!
Your children will be very excited to spend two weeks at a very magical Walt Disney World. It will allow all of you to not only enjoy the four great parks but also the water parks, Disney Springs, and a multitude of choices for recreation.
The
Disney Deluxe Resorts will offer the largest rooms on property. Each of these resorts will also offer a variety of suites from one bedroom to massive two to three bedroom beautiful ones. When booking a suite you will also receive Club Level privileges even if the suite is not located on the Club Level floors.
Some of the Moderate resorts will also offer suites but that is not the norm. You can also reserve a Disney Vacation Club property when it is available. Most of these locations offer 1and 2 bedrooms suites and there will also be a three bedroom one but those are difficult to book as DVC members grab those quickly.
My favorite location for large suite type rooms is the
Old Key West Resort. Prices are more reasonable then booking a suite at a Deluxe Resort. The two bedroom units are HUGE and there is a king bed and full large split bath in one bedroom. The second bedroom will have two queen beds and attached bath. There is a large living and dining area and of course it comes with a fully equipped kitchen and washer and dryer. You will also have either a patio or deck to enjoy.
Hope this helps give you some options to consider for your upcoming vacation!
