First off, Welcome
Ya, I'd say you are riding a little short. You don't mention if you frequent the park. Don't know if you plan on doing such a trip every year, but I would suggest an all mountain ride in the area of 156 / 158.
Boards that would serve you well (no Park) on this trip and when you get back home:
K2 Turbo Dream
Jones Mountain Twin
Rossi Templar / One Mag
Others will chime in I'm sure. But those three are solid no brainers.
Get it. Wax it. Ride it.
