For me it would be all the times I've been in Majorca in Spain. My girlfriend comes from there and it's a beautiful island. I visited many places there and love all of these. I've been there 5 times in two years, hopefully I don't have to pay for an hotel there so I can make the travel easily. I also made great friends.
I also worked their at my girlfriend's mother's restaurant, great time, even tough it's not my usual working field.
I would also mention a backpack travel I did some years ago, around France and Belgium. Funnily, I met a Smash player in an hostel, he was from California I think. We drank in a bar in Brussel with a brazilian guy and, if I remember right, two flight attendant that were waiting for their next fly, or something like this. We drank some beers before I got too drunk and had to go back to the room. Was super funny.
Best place I've ever been too?
A week in Rimini, Italy and San Marino in mid 2017. An amazing trip and also signaled the end of an era in my life a week after. Went to Italy before but was ehhhh....
Travel can literally change your life. I hope it changed an era of your life in a good way.
