Rick Steves Audio Europe did you download all of them

It was several years ago, but I think I downloaded them before the trip and listened to many before I went. I particularly remember the one of the Sistine Chapel. This was pre smart phones and I was loading to my iPod. I got shared ear plugs so my daughter and I could sit on the bench in the back of the chapel and just look up and listen and share the moment. I learned so much.

You'll need a internet connection to download, so yes, do that before you leave home.
I only download things that I think will be useful, and some things are best to listen to before the trip.
I rarely use everthing I download.
It's easy to delete things you no longer need.

Are you going on the RS tour? If so, I would look at the detailed tour itinerary and see what walking tours and site visits are included. If the tour covers it, you probably don't need to download any of the walking tours, but for places you have free time you might want them. For example, but there's a detailed audio tour of the Accademia and the statue of David. But the tour visits with a guide, so you'll listening to your guide in real life and won't need the audio tour. The only time I've used one of the RS audio walks was traveling on my own (without a group).

The app has both guided walking tours but also general interest stories and interviews from Rick's radio show. It would probably be impossible to listen to every single one of them while on tour - because you'll be doing tour things during the day. You can always go back and listen to episodes after the fact.

I think its a great app. I typically download everything of interest for the cities/countries I'm visiting. I find that I listen to them during down town like plane, etc. I also listen to some before I travel when I'm driving or cleaning.

Yes, I download them at home where I have good WiFi. They don't take up much room
