I own a Seaquest Passport BCD, and it performed very well on about 15 dives during my most recent vacation to Bonaire.
Pros: very lightweight (< 5 lbs), weight-integrated (20 lbs max), right rear pull dump, several D-rings, mesh bag which folds into lumbar area and provides lower back cushioning when not ensheathing the entire BC, more than adequate lift capacity (my medium-large 28 lbs lift), price: about $250
Cons: weight pockets held in by Velcro (may wear out with time), lack of non-ditchable trim weight pockets, no carry handle strap
It's hard to beat the Passport for travel diving. It folds up quite small and weighs very little. The trade-off for such a lightweight BC is ruggedness. I suspect that this BC would probably breakdown faster than other BCs that I've used (Seaquest Pro QD+, Scubapro Nighthawk), but this is a consequence of using such lightweight materials to build the BC. An example of this is the multiple plastic D-rings that can be found on the BC.
At the risk of giving you yet another BC option to consider, I would highly recommend a backplate and wing (BP/W) setup, which would probably pack down smaller than the Passport with a negligible increase in weight. I recently transitioned to such a setup for my non-travel diving. Knowing what I know now (that my trim is far superior while using the BP/W), I would recommend that you do some research into this (right here on ScubaBoard) and try out the BP/W on a test-dive. The BP/W is most commonly associated with a "techie" or DIR setup, but I can assure you that even non-DIR divers like me appreciate its advantages. In your case, an aluminum backplate + wing with a one-piece harness might be the way to go. A top-notch BP/W rig can be pretty reasonably priced at just a little over $400. Try Deep Sea Supply's website. They make great gear.
Good luck with your search...and enjoy your vacation diving!
