I would either check with shore excursion Group or download Shipmate, which uses the shore excursion group to book excursions. Plugging in the dates on the shore excursion group website seems to produce inaccurate results. It calls it a 20 day cruise arriving May 3. Shipmate calls it a 22 day cruise.
logically, we are sleeping through most of the time change. To give a brief example, we will be getting an extra hour of sleep and resetting back on the ship as opposed to “traveling to the future”.
(Making up dates and times)
Ships time vs “real time”
20th 8:00 pm vs 21st midnight in Brisbane
in 4 hours we’ll call it the 20th again and keep sleeping away the difference.
This is obviously a simplified explanation, but I know we are arriving in Seattle on the fourth so shore excursion group has something messed up.
