We quite often get a double (straight up) from one bar and immediately another from a second bar. Comparing the two glasses side by side can often show a difference in the pour. I just attribute it to the bartender's being a little rushed at times.
After having the Plus package for a few cruises I've come to realize it's not the bargain I once thought.
We're returning to paying our gratuities & getting the setup for coffee.
I would concentrate on the shows more than meeting new people. You can meet them all day long or after the show at any of the other venue's or bars. The production shows are only presented twice (early and late) once per cruise.
Just a tropical shirt & shorts (if you prefer) for the dining room. The waiters all had tropical design shirts on.
Most people just had casual clothing & it didn't appear to be much different then any other night.
Unless I'm mistaken, the only time they provide a shuttle bus from pier 21 to terminals 2 or 4 is when your initial cruise returns to a different terminal. Normally there is no need for it.
It's a little far to walk with luggage, although there are sidewalks.
