Your first consideration will be defined with finding a Resort to sleep a family of 6, correct. ? Maybe give us more info about the youngest ages in your group and would a paknplay be comfortable for that long stay? Also do you want just a mini frig or a small refrigerator in room.
DisneyWorld has cash rooms and also
DVC resort rooms .
In general my first response be a monorail resort (Poly Contemporary BLT or GF ). With this age group you would want to be closest to the MK. Also staying on a monorail resort gives you lots of simple selections to jump on monorail and go to the Different resorts to visit the lobbies or the restaurants or the gift shops which is a wider selection if it happens to rain Or somebody needs to take a nap and the others need to have something else to do… Any other location means you are basically stuck in a hotel room with a TV and a restaurant and a QS to choose from. Also you can walk from the Contempory or BLT Bay Lake Tower to the MK if their are other delays with transportation … due to weather or breakdowns… But I am not sure about room capacity for your family. And also budget . But if I had a small family I would think they would be just as fascinated with taking a monorail or the large FerryBoat or the smaller water boat taxis, etc as actually going on an attraction.
The other second best choice would be a family suite at Art of Animation because this resort is a simple walk from AoA over Bridge to the SkyLiner or walk to POP Century ( must be Preferred Pool View when making reservation for me) so more gift shops and quick service and so much “Disney” theming to walk around and explore at both resorts! I love POP and I have a reservation for first time at Art of Animation in September for myself to check this out.
Be sure to check room charts and amenities, etc. online.
This is your first visit and I suggest you consider more than just the swimming pool… Also a stay at one of the monorail resorts includes the simpler viewing of the fireworks from these locations and also the nightly Electric Water Pageant Parade which would delight this age group..
My grandchildren (visits from age 3 up to 14 ) and their first visit was going home to rewatch the Electric Water Pageant over and over online since we stayed at Bay Lake Tower and still they want to stay at BLT with every yearly visit… And must see the Water Pageant… or the visit is not a success. And the first dining reservation always must be for the SciFi at HollyWood Studios!!! That is all they ask for and hope and dream of . BLT, Water Pageant, Fireworks and SciFi.
