I am 61 years old.  I go to WDW solo, and my DH stays home.  I have an old flip phone, and I love this one.  I don't want to part with it. The phone will text, but I don't use it that way. The plan that I originally chose did not include texting, and I have no plans to change that. The phone also has a contact list, but I never put even one phone number into it.  I have my lap top at home, but I have no plans at all to bring it with me on vacation.  I do not need to be  THAT  connected.  I do usually keep my cell phone in my pocket, though.  
I made all my Fast Pass +, and I am all ready to go for early December.  I figure if I need to change any FP+, I will just go to one of the kiosks in the park and change it there.
No .... I don't want a  "Smart Phone"  yet.  I'm quite happy with my dumb phone.   LOL
