My wife, daughter and son in law just got off the Sunrise on Sat 1.25 Ports of call were Amber Cove and Grand Turk.
A storm occurred while we were on Grand Turk and that caused some problems with the excursions. The kids took a snorkeling excursion and us senior cruisers went on a tram ride around the island. Of course the storm hit as we were as far from the ship as possible.
The OP has many great points both (+) and (-). We had never been on the Triumph so we don't know the 'before and after" aspects of the remodeling.
Pros for me.
I liked the new Liquid Lounge with the chairs instead of the benches. (as previous Carnival ships I have been on had)
The comedy club lounge was awkward to get to and too few seats.
The staff. WOW . They were great. Helpful at every turn. The Behind the Fun tour was exceptional. I highly recommend it.
Embarkation and debarkation.. Easy as pie. We carried our own bags off the ship, but we pack lightly compared to others.
My daughter and SIL want to book another Carnival cruise.
Art Shake Trio featuring the electric violins were superb.
The amount of storage space in the cabin was outstanding.
Our rooms were in the 8380's neighborhood and noise from the ninth floor Lido was never a factor.
Con for me
There were times when I felt there should have been more bar tenders during busy times.
It was a fun trip and we won 2 Ships on a Stick. yeehaw.
