Hi!
I’m now 69 but have been travelling solo many times.
Copy all your documents, itinerary and tickets and leave paper copies with someone at home.
Copy them all into secure email or into “Notes” on your phone or device, to bring with you.
Take screen shots of all your airline info and boarding passes , and prebooked Museum etc tickets, as you go, including the barcodes.
Keep those screen shots in your “Gallery” on your device.
Then you can show them as needed, without needing data or wifi to access them.
Put all the names, addresses and phone numbers of your accommodations into your device before you leave home.
Be sure you know how to make phone calls in Italy, to Italian numbers and to home numbers.
Download the Italo and Trenitalia apps.
Trenìt!, I believe, has both on it, and will give you real-time platform info, train ID numbers, and times.
Be sure to have Google Translate downloaded.
It will let you put in key phrases and save them in Italian for when you need them in a hurry.
IE:
Help.
I have a reservation….
What time is the train leaving….
Where is a good restaurant near here…
I’m ill and need help..
Etc, etc.
Be sure to have WhatsApp on your phone.
Practice at home first.
It works with other people who also have it on their phones.
You can talk, text and video chat with it for free.
Pack light….you have to carry it and get on and off trains, sometimes quickly.
If you use Tylenol or ibuprofen, bring plenty with you.
It’s expensive in Italy.
If I think of anything else, I’ll add it later.
Have a wonderful trip!
You’ll love it all!
