Our group, myself and DH-49, DS-19, DD-17, we also had my auntie and uncle along, both 49+ and 3rd cruise for us all...
Overall, we thoroughly enjoyed the cruise. As some other reviews pointed out, yes there were lines, it was not a private charter...occasionally we did smell the "odor" and it did smell similar to sewage or other sulfurous odors...but it was very sporadic and it dissipated quickly enough...
Boarding was the smoothest ever...line moved quickly, several of our carry on bags were hand searched as they contained bottles of sugar-free torani syrup and sugar free juices...I'm sure it looked like liquor bottles on the x-ray...the worker searching the bags just looked at the bottles and by the last bag he just asked, "is it the same thing" yep...we take along lots of sugar free products...even the individual powder mixes for water bottles. Check in was super easy and efficient...given zone 4 and waited a bit...then off we went.
