My excel file easily has 15 tabs.

On our "first" one-and-done trip, I had multiple itineraries options printed for each day so we could be "flexible"

I've been making spreadsheets for my trips for 20 years since my honeymoon! Knowing I will see what I want to see, do what I want to do, not miss out on things and get my money's worth
IS relaxing for me. Not planning is stressful. FOMO is stressful. The hubby doesn't like militant days (so I keep that in mind when planning) but he does appreciate it when I plan because things go smoothly.
I loved 180 days ADRs. There should be a reward for us uber-prepared folks!
