We will be arriving from a very long 15 hour flight in Auckland at 5:15 AM on Good Friday 2023. Our hotel check-in time isn't until 3:00 PM (though I am hoping they will at least keep our luggage for us). What is likely to be open, not too strenuous and a "must-do". We are cruising out the next day but not until 8:00 PM, so any suggestions for the Saturday would be welcomed too.
