This looks great! I may try this out for a summer trip. We plan trips amongst 3-4 of us. We've used Notion before, but my wife and friend couldn't understand it. We've used a Google spreadsheet and that works OK (using travel planner template). I used a Google doc this time and it's honestly better than the other two, although in Notion I _did_ like the ability to calculate trip cost and budget using tables + calculations.
