We have about 2h15m between SFO-LAX arriving in T7 and LAX-SYD boarding. I've got access to the UC, Alaska Boardroom, AC Maple Leaf Lounge, and Star Alliance Lounge in TBIT for all four of us (self, Mrs C, C Jr 1&2). I've never been to the Star Alliance Lounge before, but will get to experience that in July on another trip.
Is it worth schlepping everyone through the tunnels for what looks like a 15-20 minute walk, or should we just stick with the UC (incidentally, I haven't seen the "new" UC in LAX either)? Does conventional wisdom change if I factor in that Jr 1&2 will likely be peckish?
