I would suggest planning the best you can on staying health. Plan to eat outside as much as you can and away from people, even if that means ditching table service for quick service and finding a somewhat empty spot (10 to 15 feet away from others probably is fine, especially if there is even the slightest breeze).
Then, your best bet is an N95. Moldex makes some really fairly nice N95s and (at least as of a few months ago) they are made in America. The AirWeave masks actually cut down the resistance you feel a lot (because more surface area) and almost feel like the ones with a valve on them (except don't get the valve ones, you'll be asked to use a different mask!).
They also have a more comfortable fit, especially on the bridge of the nose.
Keep men clean shaven and those will stop 95% of particles from passing through the mask, combined with distancing, you're extremely unlikely to get enough of a viral load to be infected, especially since you're vaccinated. They're a bit expensive, especially for a family, but if you want the best protection that could be one option.
I personally have been using the 4800 version which had a soft foam face seal and a strap that you can adjust for a snug fit. I personally have been able to make one mask stretch for a week (I work four tens and probably half the time is in my office with the mask off) but for Disney I'm planning one one mask per day. Try not to touch the front filter of the mask and especially don't touch near your mouth or anywhere else on your face if you do touch that. Practice putting them on and taking them off without touching that front filter part. Have hand sanitizer (70%+ if you can find it) and use it after each time of taking the mask off or putting it on. I personally plan to keep the mask on indoors and outdoors since it's easier than taking it off on rides. It's just what it is this time around...

They're not cheap (about $65 for 8)... I've spent probably $800 since the start of shut downs in 2020 but I feel very safe with them and I haven't had an issue with the bridge of my nose hurting or anything.

These might be a little less comfortable and you can't adjust how tight they fit your head, but they are sold in a smaller size for smaller faces...
