Went on Valiant mid-April and it wasn't very drunk party at all! Dock/Dock house was relaxing to hang out if you get a lounger, board/card games by the arcade, or deck above the pool deck with swings/private couch things with the numbers.
It was slightly odd, as when I did want a drink, there weren't as many servers serving drinks on outside upper decks compared to Royal/Celebrity/NCL (I.e. pool or near mid/back upper deck). I also found the bars kinda just meh tbh, Sip was nice - but limited seating and lighting was too bright. The overall bar setups, didn't seem condusive to sitting around but moreso grabbing a drink to bring somewhere else.
Crowd was the most diverse crowd I've been on a cruise before (in a good way). Fellow sailors also seemed way more considerate and quiet compared to other lines (hardly any cabin noise late night or early mornings on deck 11). Soda being included was also nice.
