Let me first start off by saying that we stayed in a Spa Suite, which drastically altered our cruise experience.
The benefits of being in a NCL Epic Suite are simply wonderful. You can literally cruise within the cruise. It's full of exclusivity - a butler, concierge, private areas, a private restaurant, lounge, priority embarkation & disembarkation, premium seating for popular shows etc.... Additionally, we had access to the common areas of an absolutely fabulous spa. The pampering is worth the additional cost (at least while on vacation :-). Customer service is A+ in those exclusive areas.
Le Bistro was awesome!!! - great filet, great mushroom soup.
The shows were very good. Blue man was different, but certainly entertaining. Legends was also good, MJ was the BEST, Britney was barely average, and Rod was fair, but certainly better than Britney. Second City....funny, funny, funny. We saw the Murder Mystery & a few of the improv shows and NCL picked a winner with that group. Cirque was good, but there could be less of a story line and more showcases of talent. I read another review that said the meal wasn't enjoyable. I think they've improved it, since we enjoyed it.
The ship's decor, simply beautiful. There was so much cabinet space in our suite and the decor was our style preference, modern and interesting.
The practicality of the room design is nonexistent. Every time one of us took a shower, we has a mini flood in our room. The drain is on the opposite end of the front curved door that doesn't seal, so the water piled up by the door (the floor is not level) and flooded, EVERY TIME we took showers. We felt awful requested that our steward come, who had to get down on her hands and knees to sweep the water into the drain and carry out 6 or 7 wet towels. After a few days of that guilt, I would stay in the shower an extra 10 mins. to use my foot to sweep the water into the drain. It was really bad. The curved doors look nice, but they get stuck on the track and don't seal, even when going to the bathroom. Awful combination. Again, the room is beautiful, but certainly not practically (with the exception of the cabinet space).
Label these mystery light switches NCL, or leave user instructions. We were confused about the setup for a few days and had to request assistance from our Butler.
Expand your room service menu options for Suite owners (in fact, for everyone). If I want to eat in, and I'm willing to pay for a meal from one of your specialty restaurants, or if the private restaurant two floors up is serving something I like, allow the Butler or steward to bring it to me. You profit from the specialty restaurant orders. Holland offered the option of having what was being served in the main dining room, as room service to suite owners, and we loved that option.
The Spa employees need a bit of an attitude adjustment. I had every intention on paying for spa services, but quickly noticed that previous service customers, waiting spa services customers, or those who had purchased the high-priced products received great reception, but when I wanted to make use of the spa (that I paid quite nicely for), pleasantries declined. All is well though, I kept my additional money.
Service in the public bars and restaurants was average, at best. We only ate in one public restaurant - O'Sheehan's. Great milkshakes, yummy, but the service was typical of a fast food restaurant.
Teppanyanki (sp?) - A little bumpy. The hostess tried to get us to wait until 6pm, when we made reservations a month prior to sailing for 5:30pm. Apparently, another family was supposed to show, but was running late. WHAT?!? No, we will not wait an extra half hour for them. I was extremely hungry and I noticed that the server still tried to slow walk our appetizers to wait for them. That put a bad taste in my mouth, and while the food was fairly good, it was on the salty side. By the way, the family never showed.
Yes, NCL will try to get you to spend as much as they can while on board, but they also offer a lot of perks and new/different cruise options. I was ill one night and my husband called our lovely Butler to request a ginger ale, she brought it of course, and the charge for a soda showed up on my account the next day. Really? I paid how much for a Suite, and NCL couldn't cover the $2.25 for a soda I requested for an upset stomach. LOL
Bring spending money and expect this question at nausea, "Anything from the bar?" :)
