Deck 12 port side — the afternoon sun situation
If you book a port-side balcony on Deck 12 and your itinerary goes south in the Caribbean, you will have direct afternoon sun blasting your balcony from about 1pm to 5pm. This sounds nice in theory. In practice the balcony furniture gets hot enough to need a towel under you. The glass divider magnifies it. We loved it the first day and hated it by day three. Brought towels from the pool to cover everything and it became manageable. The room itself is excellent — standard Harmony balcony, well-maintained, no issues. Just know your sun exposure before you book port versus starboard. Starboard would have been better for our route.
