5 senses gift ideas - help!

Hey everyone! So my boyfriend and I are going on a trip over Valentine's Day and I wanted to do something nice for him! I was thinking of the "gift of 5 senses", so something for sight, sound, smell, taste, touch. For sight i already have new lingerie, but struggling for the others. Thinking a Spotify playlist for sound, some chocolate for taste, maybe lotion for touch? Not sure on smell.

Everything needs to be small/airplane friendly. We'll be sharing a suitcase so I'll have to be extra sneaky with it (planning to put in a pocket we never use)!!

Thoughts/suggestions please!!!!
