Hey there and welcome to the Community!
I hope you will enjoy your trip and Spotify.
You will be able to play Spotify everywhere as long as your subscription is on.
If you go for trip to long time, ensure that you purchase Spotify for some months, just to ensure you will be enjoying Spotify the whole trip!
Hey! Welcome to the community :)
hpguru is correct.
You can use your premium account anywhere in the world for as long as you like, providing you continue to pay for it using your US payment details. You can either do this by subscription or purchase several months in advance whilst you are still in the US.
