Well, I'll be darned.
If I'm not mistaken, they were identical way back. You have an extra day - never really noticed that before. Was that true all along? Was Mazatlan originally on the itinerary?
What a sec - 10 ports vs. 9?
Funny thing - I'm counting 8 and 7 ports, respectively. I don't count first and last as "ports". I only count stops enroute.
And I still count you as having 6 sea days. That's the 5 listed as such, plus day 5 in Panama - which arrives at 8 PM (mine is at 6). That counts as a sea day for sure - even if you can go ashore that night.
