Absolutely! Any extra convenience just might not be worth it.
When you're the "tour guide" the amount of paperwork is phenomenal. On our lengthy trip last summer, I had 20 plane tickets
alone to keep track of. Never mind the show tickets, etc. DH doesn't really understand how complicated traveling with a family is, but he does appreciate the effort quite a bit. Actually, the whole family does. I don't think they have ever once complained about anything I did. Maybe they just know better!
Right now I'm just figuring out how to get the most I can onto the ipad/iphone. It was a huge accomplishment to figure out how to get all my Disney reservations in one spot- but I did! I was able to email the entire "Your Reservations" page to my phone in one shot. So I don't have to write down all those ADRs, reservation numbers, etc.
I wish I could get boarding passes on the phone but my little airport doesn't have the technology, LOL. In the near future you'll probably be able to scan in the value of the Disney gift card- or any gift card- to your phone (though I'm not sure I'd trust it entirely).Of course, I'd better keep the phone WELL charged if every single travel arrangement resides on (and only on!) the phone.
