We were on HAL’s new Westerdam this past August, round trip from Amsterdam. The co-ed spa was very nice, and thalloso-therapy pool the best ever. The men’s changing room had 2 nice showers in an adjacent area to the mens locker and benches (with a door). The men’s private, dry sauna (w/ view to the sea) down the hall, would suit maybe 6 men. The sauna room was rather hot and there were two showers in this private men’s only area as well, which was great for not having to put shorts back on.
We will be on the Crown Princess September 30, 2023 and looking forward to it. 🙂
