Travel Songs

[myway25]

Hey there, I'm not sure if this is the right place to ask this (so please move it if necessary).

My friend is going to Europe for the summer and I'm writing her a long plane letter. I really want to end off with a nice ayu song (copy and paste lyrics).

Which ayu songs (in terms of lyrics) would you say is summery and fits my purpose. I've tried searching but there are just so many songs and i can't remeber what the songs say. EX: fairyland seems like a happy song but the lyrics don't really reflect that.

Thanks so much in advance!
