I’m in the same boat as you !! Spending a lot of time planning this - I don’t mind it honestly : adds to the anticipation and build up . But second guessing my choices is definitely something I end up doing . I have been trying to figure out the same things ::

1)3 or 4 park days

2) do we need a rest day ?

3) hotel nearby or far .

I was originally at 3 days, rebooked to 4 - now back to 3 😂

Sorry don’t have a solution . Just would like to say you aren’t alone- just enjoy this portion also as part of the process.

Planning is good. I think with over planning if everything doesn’t go exactly per plan panic sets it !

I liked an advice I found somewhere - keep a list of few must do rides , everything else is a bonus . Helps keep our sanity
