Since it appears to be just the OP and the child the fast pass runners, helpers during potty breaks and child swaps won't work for her this time.

My apologies...somehow I missed that part....I was reading several other threads about the sametime, and maybe only focused on the headline. My Duh!
Nevertheless, she could still do two of those while the child naps: collect fastpasses and use the restroom.
All that said, I will make a further suggestion; I've been in the situation - short term - of being the only adult watching several children - it's an extra challenge.
My suggestion - and I don't mean this to be insulting - I felt like I had to be on my toes as much as possible. If you are the ONLY adult- then doing something like getting on the bus, the shuttle boats, and closing a stroller - is quite a challenge. I found loading onto the parking lot trams especially scary as a solo adult- just because loading a sleeping child and stroller is a two step process. You almost HAVE to wake the child while you load/unload the tram.
I stand by my suggestions above- but would add the caveat that as the only adult- I'd try to be proactive and avoid getting to the point that the child is sleeping in the stroller - BECAUSE - at that point - YOU will also most likley be somewhat tired.
I've been to WDW - recently with children that age - and at least half the time - the children- aided by the stroller - had more endurance than the adults in our group. I know all children are different. Truly, I can go on little sleep, and I was the ONLY person in our extended family group who slept (slightly) less than the kids. Cumatively, everyone else slept as much as or more than the kids- because the adults are doing more walking, stroller lugging, everything lugging, navigation, mental planning- especially if youa re doing it all your self. It adds up. Odd things can come up unexpectedly when you are out of your normal element. I'm not trying to scare you - you'll have a great trip I'm sure. I'm just saying, my personal comfort level is compromised if I'm tired.
If I was the only adult, my personal approach - would be to consider napping with the child, or maybe doing something very safe like hanging out on the room balcony while the child naps.
One trick we used many times over- is the pool break. If your energy level or the child's are not quite in sync- consider a trip to the pool, hot tub, or a simple bath/shower. For some reason showers are the least effective of the above. Whoever has the least energy, takes more of a 'soaking' approach. (or sitting by the pool) Whoever has the most energy, takes more of 'active' swimming approach. Even if the kids have slept in a car all day, while the adutls drove- a bath or pool dip gets everyone ready to sleep. And the pools at WDW are great fun! So my approach would be to plan daily pool breaks at some point in the day.
