I love your report and your pictures are all great! You really captured so much of the theming and ambiance around the ship, and I didn't get as many pictures of things like that. It sounds like you managed to fit more activities and entertainment in than we did, and I couldn't tell if maybe you had a little bit smaller crowd (ours was a spring break cruise, so was definitely very full!). Though that diaper dash picture looked incredibly crowded! We did several character meets, and a fair amount of pool deck time, either riding Aqua Mouse, or watching funnel vision (I saw at least 4 entire movies up there, and parts of others), so maybe it's just that we did different things. I also get pretty wiped out by around 10pm, so it's rare that I'm going to be starting anything after that! If I had known about the Arabian Nights at 10 though, I would have loved to see that!
I also love your excursion in Cozumel. We've been 2x, once to Nachi Cocom and once we did the reef restoration / snorkel. I feel like there is a lot to choose from there, and none of it is too far of a drive.
I agree with so much of what you say. The overall theming of the ship is fantastic, the lounge theming is great too, and I love that they are in a more central location. I agree they are lacking in quieter spaces, and they definitely need cushions on deck 4 loungers! The layout was definitely not a deal breaker, but it really did seem odd/unfortunate with the upper deck dead ends, deck 4 not wrapping around, and the cut off adult space.
Despite a few shortcomings, I also would happily sail Treasure again, and I feel like there is plenty left that I could explore and experience, so maybe sometime in the future! They would have to mix up the itineraries a bit though, I've done eastern and western now, and for me it's more about that than anything to do with the ship.
