So I just booked my August 2020 trip this week. I would like to start a spreadsheet that I could share with my wife, that has all of our plans in it. Ideally I would like to have it online so that we could also view it from our phones when we are in DW. What planning tools does everyone use? I could create a google spreadsheet but she wouldn't be able to edit it, because she doesn't have a google account. Are there any other helpful tools out there?
