That looks like a really nice lounge experience! Glad it's all working smoothly so far. That last minute bar bill seems to be a relatively common occurrence, or maybe we're just unlucky. On all of our prior VO trips, we've had a small bar charge added overnight on the last night. Fortunately, we've been able to get these adjusted in person before leaving the ship, but I will say that the last time it happened, the gentleman manning the guest services desk argued with me a little bit about it - politely, but he didn't just immediately accept my assertion that we hadn't incurred the charge.
Anyway, looking forward to hearing more about the rest of your journey!
