Cove Cafe - It always looked closed. Great coffee. They also have appetizer snacks late afternoon/early evening.
Onboard Airline Checkin - Leave your luggage outside your door the last night. You don't have to bother with it again until you arrive at your home airport. You don't even have to have it with you through customs on the ship. No trying to find it at the port. No lugging it off the ship, onto your airport transport, or in the airport. It was awesome
Remy - It's 100 times better than I thought it would be.
Pirate Night Buffet - I was disappointed, because I was used to the traditional cruise midnight buffet. It's really just extra food, nothing really artistic or cool.
White Wall Verandah - I wished I had understood the different between the white wall an the regular ones. It's not a big deal, but your view is blocked a little bit. The regular ones are more expensive though.
Drink of the Day - It's not available at all bars. Not all bars, like the small ones on the pool deck, can make any drink.
Souvenir Glass - It's plastic.
Castaway Cay - There's a kids club there too. Lounge chairs fill up fast near the beach in the shade, not with people, just people's stuff
The glass bottom boat excursion is just OK, probably not worth the money. You can wait to rent snorkel gear there. They never seemed to run out. We reserved it ahead of time, but I felt bad and didn't use mine. We didn't realize that there's a water slide on the island, but DS doesn't really like them anyway.
Mickey Bars - Besides room service and MDRs, I still don't know where all you can get them. I should have gotten one
Toiletry Samples - The shampoo, conditioner, and lotion provided are really big. You could probably get away with not bringing your own, if you aren't picky and don't have skin allergies.
Rent Shoes - Men can just rent dress shoes. You don't have to rent the whole tux. It's helpful if you don't want to bring those big boats in your suitcase for 2 meals.
Pictures - Don't wait until the last day or night. It gets really busy.
Mixology Class - Do it. Sometimes the Disboard meet group will organize one for them, but you have to know about it in advance. I wished we could have signed up with that one, but the one we did was still awesome.
Fish Extenders
Decorate Your Door - Bring magnets or vinyl cling to make it more homey.
Skyline Lounge - Awesome decor and drinks. Plus, they offer a passport where you basically get a drink, maybe two, for free if you purchase so many.
Views of the Sea - They are actually fairly limited, especially from most of the bars and MDR. However, the bar between Remy and Palo has excellent views, including the sunset.
Karaoke - Happens pretty late, so I never got to do it with my son.
Small purse - I wish I had brought something with which to carry around my room key, lip gloss, hand lotion, and phone. I did have a lanyard to carry my room key, and once they convert to magic bands, that won't really be a problem. However, my regular purse was just too big. I looked to buy something on board, but most things were D&B (expensive) or more for kids.
Excursions - I wish I hadn't booked ones with food. You're already paying for food on the ship, and usually the excursion food is just OK at best. However, some excursions are not available with the food.
Dunns River Falls (Jamaica) - I wish I had known that there was a paved trail next to the falls. We went a long time ago by ourselves and felt it was a bit scary for our DS. I would have done it, if I had known there was an easy path. We'll just have to do another cruise, so that we can do the falls
I also heard that there's chicken exits on the underground river excursion (Cozumel I think). I was worried our DS would freak out, and we would be stuck in a deep dark cave with a panicky kid, so we skipped it.
Embarkation/Debarkation - I wished I had known earlier that we needed to be on the ship by 3:30pm in PC. We bought a multiday ticket to KSC but only used one day. I prefer to get the earliest embarkation time possible, to take advantage of the pool and food, for which you have already paid. Plus, it gives you time to sign up for classes and explore. On debarkation day at PC, they really boot you off the ship early, by 9am. We ended up with a lot of time at MCO. Luckily, the Disney stores at MCO have an awesome selection of stuff. I even found stuff there that I hadn't seen at the parks or online. There's also a Universal store.
Pressed Pennies - They have
DCL pressed pennies at the terminals. I should have looked at the press locations before we went, because now I can't get one until we go again. So, we'll just have to go on another cruise to get one
