Hello waterpark,
After almost 2 years pcs I can say I've debated the "going to the mall thing/ going out for a bit " more than a few times.
Sounds like you need a break, sometimes it's nice to do something normal
Just take it easy and bring a snack and water and maybe extra pain meds if you need.
I learned now that I have to have a snack with me because making all the shopping decisions is exhausting.
Bring earplugs if the music can be loud.
Take it easy

and stay far away from food courts or anything overwhelming. It is easy to not realize how far you end up walking.Take breaks.
I try to almost meditate on the way there. Just close my eyes and breathe in the car and save all my energy. Sounds like if your daughter drives you will be able to relax.
Hope everything goes well and that you find something cute
p.s. I can only go in the mornings when my energy was higher, def. if i went in the afternoon or night it would have been too hard.
