I really really like the vibe. Hits that "sunny resort area" just right :)
I love the horn that comes in for the second half of the track! They feel so natural and really enhance that summer vacation vibe :)
You've done well with that MIDI guitar. My advice for next time you use it would be to play with the velocities a bit more so it sounds less copy/paste, adds dynamic to the strumming, and helps it 'live' in the mix. I'd love to have heard some guitar plucking too to add variation.
You've done a wonderful job of matching the setting, and the mix is good
