Disneyland newbie - Advice on how to navigate the park

I am planning a trip to Shanghai Disneyland mid-March next year with 2 young kids (4 and 6) and am looking for advice on how to minimize the amount of time my kids will need to stand in line and yet maximize our experience. Moving around the park will be a little slower as I don’t want to be rushing the kids too much to run around the park.

There’s also a chance that my younger child may not meet the height requirements for Tron and Rex’s racers.

Monday Afternoon - Check into Toy Story Hotel - Walk around Disneytown

Tuesday - Any tips on what I should do when I enter the park during early access? Advice on which rides I should head for during this time? - Do you think it’s worth it to fork out money for premier access to illuminate?

Stay at Toy Story hotel

Wednesday - I suppose Day 2 will be heading to all the places we have not visited or is there anything I should specifically plan for this day?

Thanks in advance!
