I don't travel much, but the Planet Fitness I went to is better than any hotel gym I've seen. By a long shot.
No barbells, but three Smith Machines (the nice angled kind, not straight vertical). Several flat/incline/decline free standing benches. Dumbbells up to 60 pounds (not gonna lie, it was fun getting dirty looks shoulder pressing what most other people were chest pressing, but even that got old pretty quick).
A ton of machines, including two weight stack leg presses, and a nice cable setup (really sweet dual pulley for overhead stuff). Two dip/chin stations - one assisted, one not. Ab area with knee raise stations, decline crunch benches, and Swiss balls. And of course plenty of cardio (the ARC trainer was pretty nice, like half-elliptical half-stepper).
If you can't get a more-than-halfway decent workout there, you don't know how to program training. Even Wendler has mentioned using crap gyms for an assistance-only day. It can be done easily, ubermacho "fuck PF"-biases aside
Nope. Seriously, nope.
