Great trip report!

What was the temperature difference between Auckland and Tonga?

How close is the IDL Hotel to the IDL? Does the hotel belong to any big hotel group?

Which time zone is Tonga in?

How many times did you cross the IDL during your cruise?

For your UA842 flight on the 19th, was there a special designation so that it won't be confused with the flight leaving 4 hours later?
