We stayed in a Neptune Suite on a Panama Canal Cruise. The ship left Fort Lauderdale just after the hurricane hit Florida in Sep. 2017 and there was very little communications from HAL about the status of the cruise.
Embarkation was smooth, but not like the videos where someone shows you to your suite. We found it on our own. The suite was roomy with a nice veranda. The bath was nice except for having to climb into the shower over the bathtub. My wife had trouble with that. Some nice amenities come with the Neptune suites, including breakfast in the Pinnacle restaurant and the concierge lounge with very good snacks and helpful young attendees.
I've seen comments about noise from moving deck chairs on the deck above. In the 14 days, we heard this, maybe twice and it was a non-event.
Nice city tour. People try to sell you everything at the stops.
Bus had no shocks. Long ride to Antigua. Guide was below average. Transferred to a smaller set of busses for going through the streets of Antigua. These busses rarely stopped for pictures and it was difficult to take pictures because of the bumping and rolling over the cobble stones.
