Mine are 4x6. I prefer WordPerfect and that's what mine are done in. I can email it to you if you have WP. Anyway, at the top, I have the park, day, date, hours of special events (parades, fireworks, etc.) that I don't want to miss. Also ADR #, time & place. After that, I have my touring plan, which only goes through lunch or a little after, as we will be taking a break at the hotel. I have all of the rides/shows color-coordinated as to which "land" they are in, so I know where I need to get to for the next ride.
I also did an evening card (I will put them back-to-back and have them laminated). But on the eve one, it will have the same stuff at the top, park, day, date, *eve*, times of special events (more so for eve than morn), adr #, time & place.
Then the list of what I would like to try to hit that I didn't get to in the morning, special places for photo ops, list of anything special to look for (at the stores), etc.
I'm going to punch a hole in the corner and keep them on a ring & bring the ones I will need for each day.
I also typed out cards for each park that include best times for rides/shows, where to view parades/fireworks, etc. and will be taking those with my daily touring cards. Did this for a 2-day trip this past spring & it worked great. This is the first time we've ever been for 10-nights & I'm trying to be super organized.
