Which sewing machine to take to my upcoming retreat?

This is my current dilemma. I’m flying, so I’m limited to machines that will fit in my Travelpro underseat rolling tote. Here are my options:
1) Singer Featherweight
2) Elna STAR (similar to Janome Jem 720)

Option 1: The quilt shop organizing the retreat sells and services Featherweights. I will be in good hands should anything go wrong with my machine during the retreat. I’ve also been wanting to switch out the tension assembly for one with a numbered tension dial. They could take care of that for me and giver the machine a once-over at the same time. Sewing space is limited (4′ wide), so having the built-in wider bed means I won’t have to carry a separate acrylic extension table.

Opton 2: This is my usual machine for sew-ins, classes and retreats, especially when I need more than a straight-stitch capability. It travels well and does exactly what I need it to do. The only drawback is that full throttle is a mere 650 spm. It’s fine for applique and most piecing. For long strips when you want to sew fast, it’s akin to driving a moped instead of a motorcycle. I’ll also have bring the small acrylic extension table.

I checked with the retreat organizer. The staff are bringing their personal FWs to the retreat. No retreat projects require any zigzag stitch capability. I’m taking a FQS Layer Cake Shake kit made from leftover 10″ Christmas squares and the 2024 Middle Georgia Shop Hop blocks + the FPP center block to work on at the retreat. No zigzag stitches required. I’ll be perfectly fine with my Featherweight!
