Note that this is a minor schlep and can be a tad confusing (as you'll pass the other HA lounge first, and the first signage to Plumeria will probably send you up one escalator too soon). You'll also pass through the Ag Inspection X-ray on the return to the AS terminal (typically no more than a 30 second delay). I had a minor wait a couple of weeks ago. On the one hand, while I'd typically be ok just getting an iced tea at Starbucks and heading down to the garden level, you can walk to the HA lounge in the time it takes to get through the Starbucks line.
