Years ago, we discovered that we have distant(ish) relatives (whom we've never met) on my dad's side who live in... Strasbourg. So I've definitely heard of it.
So I caved last night and ended up rebooking the Cheyenne direct through Disney and cancelling my Qantas booking. I was just so worried about issues linking everything through MDE.
Yes, I am right at the tail end of the millennial generation who really dislike picking up the phone, even more so if it's for an international call that I know will be expensive and possibly poor timing.
On the plus side though, everything is now linked perfectly in my MDE and we're all ready to go! I can even start making restaurant bookings through the app.
