I agree entirely with her assessment.
I know the Easter-apologists say it's easy to plan around these bits and that they like it that everybody's forced to have the same day off at the same time where the costs are low by their assumption.
One minor anecdote as counter to that. We went up to Auckland for the Easter weekend, figuring all the Auckland people would have headed north. We rented a holiday house in Eastern Bay that was advertised as having the linens supplied. On arrival Friday morning, we found no towels and no sheets. And it was illegal for anybody to sell us a freaking towel or sheet on the Friday. We made do for the night - luckily, we'd brought a couple of spare towels along for the beach - then bought some on the Saturday.
If you think your god says it should illegal for me to buy a towel on a Friday, or to be able to get sheets for the kids when a rental house screws things up, are you really sure that you're worshipping one of the good deities?
We did enjoy Kelly Tartans' aquarium on the Sunday though. Illegal to buy a towel but legal to look at fish.
