Two Wheels Only

I've made no such claim. Your post was related to a health and safety issue. If a cruise ship is inspected and gets a poor grade (like Seaside did), I wouldn't expect MSC's response to be "...well, ...nobody has gotten sick in the past 15-20 cruises...". I'd expect MSC's response to be to correct the issue ASAP. It's one thing to not know the rule (many don't). It's one thing to not know why the rule is in place (many don't). It's a completely different thing to know the rule, know why the rule is in place, know the potential health risk of breaking the rule and figuring "...well...nobody has gotten sick in the past 15-20 cruises...so I'll do it anyway..." Not only that, the pool cannot be reopened while the ship is in port. The ship would need to be something like 12 miles out before new water from the ocean can be added, inspected, etc. The reality is that people shouldn't do it. What you seem to be asking is that if someone does it, are they likely to get away with it. To that question, the answer depends on who is working that day, how many guests complain, etc. With a great amount of certainty, if there is an "accident" and the pool is closed for an extended period of time, none of the cruisers who were inconvenienced will think that it's "no big deal". None of the cruisers who get sick from fecal bacteria will think that it's "no big deal". It is impossible to have a germ-free, virus-free, bacteria-free cruise. However, that doesn't give guests a free pass to break rules that are in place for the safety of guests.

Keep that same energy when someone puts their bare hands on food in the buffet then puts the food back. If the health of guests is less important than putting a diapered child in a pool where diapers are prohibited, go for it. 🙄

Diapers in a water area where diapers aren't allowed does jeopardize the health of other guests. This seems like you are asking about how strongly it is enforced. That can vary from one cruise to the next so it is impossible to predict. The line is a "no, not allowed" unless specified. Certain P&O ships do allow in certain areas. MSC does not. A dress code isn't usually a health issue. The fecal matter in swim areas is a health issue. If enough people report it (photos help), it has a better chance of being enforced.

Even in the splash area, diapers/nappies aren't allowed. Very few ships (some Disney, RCCL, for ex.) have designed areas where babies in diapers are allowed. Do people break the rules and jeopardize the health of other guests? Yes.

If the OP is a Yacht Club guest, the OP gets access to both areas. If the OP is an Aurea guest, the OP does not get access to the Yacht Club areas.

You can go from Yacht Club sundeck to Aurea sundeck or from Aurea sundeck to Yacht Club sundeck. Your wristband/card will unlock the locked doors.

You can. It's easiest that way. Travel with cash is easiest but the other 2 will work. You can use your onboard account for the tips for the butler by going to the customer service desk or to the concierge's desk. You can ask for a receipt and hand it to the butler to show your appreciation. Whether or not the butler will actually get that amount is between the butler and NCL.

The dispute was related to the changes that, in part, turned Epic into the hideous monstrosity that it is today. I didn't want to get into how ugly the ship is (inside and out) because certain forum members get irrationally upset whenever anyone does. 😉

Epic isn't the best representation of NCL. It's the only ship like it for a reason. As many as 3 were planned but after the first one....no more.

My experience with the concierge service was great. He was able to get the specific stateroom that I wanted when the online system was acting up. I've been able to contact him at other times to apply better discounts and to check prices. No complaints from me. Are you sure that it was a concierge or was it a typical phone rep?

If looking at it that way, abide by the lower weight limit. In that way, you cannot be out of compliance. However, as many have pointed out, NCL doesn't actually weight anything and even if they did, what proof would NCL have that their scales are (or have been recently) properly and accurately calibrated? 20 kilos, 22.7 kilos, or 23 kilos isn't worth thinking about. FAQs and the answers given don't hold the same weight (pun) as terms & conditions. Follow what you sign/agree to and you'll be fine.

No, what is being added is a set of standard balcony staterooms on the port side on deck 15. The OP is correct that they can be booked now and the numbers are lower towards the front (15108, 15110, etc.).

I don't see it as good news for Haven guests. It's probably more of a feeling of indifference.

I don't think that will happen. If it can't be 2+3+1 for whatever reason, the mattress in the Pullman bed (in the ceiling of the smaller bedroom) can be removed and placed on the floor in the living room. It's not ideal but the steward will make it a "bed" in the evening and put it away in the morning.

How many are staying in the suite? Are you trying for 2 in master bedroom, 2 in second bedroom, and 2 in living room?
