IIRC there is a note that grav vehicles can acheive orbit in UWP planet size hours.

Umm. At 62 mph (which in some editions of Traveller is much lower than the maximum speed) it's only 2-3 hours to LEO. Also, at even 0.1G it only takes 2-3 hours to make orbital speeds. The whole process therefore probably takes about 5 hours, and the most difficult part would be getting into the right place on the right orbit with the crappy instruments air/rafts are generally assumed to have.
