@mickEblu you have been given some wonderful advice, but many suggestions aren’t possible now due to pandemic restrictions and closures.
‘Ohana is closed and there is no Sunday brunch at California Grill. Trader Sam’s is closed and there is no monorail access to the Polynesian (station is being refurbished.) Cape May Cafe, Yachtsman, Jiko, Boma are also closed. The dining page on the Disney website will give you all details on which restaurants are available. Check menus also, as offerings are streamlined (sometimes only 4 choices.)
Trail’s End is currently take-out only. If you want BBQ, Whispering Canyon at the Wilderness Lodge is very good.
Tom Sawyer Island, the Liberty Belle and Monster’s Inc Laugh Floor are closed.
Check park hours for your trip dates. The parks are closing between 5-7 pm which negates a lot of nighttime activities, including dining. Currently, dining reservations can be made only 60 days in advance. And research mobile ordering ~ it’s the only way to get food at quick service locations.
You will need to have car seats (even for a 5 year old) if you use Uber/Lyft. The cost of your rides will be higher (assuming you can get a driver with 2 car seats.)
Strollers need to be folded up on buses and on the Skyliner. Bear in mind if you choose Caribbean Beach you room may be a hefty walk (or short bus ride) to the Skyliner station.
You cannot see the inside of Be Our Guest without a reservation. (Also presently the case at any resort restaurant, since all guests are required to have their temperature taken before being admitted and seated.)
Fastpass is unlikely to return anytime soon, but be aware that park crowds have increased and that wait times for popular attractions can be 45-60 minutes. Check the app to get an idea of wait times closer to your trip.
