Hi Schwegel's, welcome to Cruise-Chat. Wish I could help, but do not know of any good on-line TAs. Perhaps a call to HAL would help. Perhaps a Google search would help. Wish I could give you first hand knowledge. We've sailed on both HAL and Princess and I can honestly say, I didn't think HAL was anymore formal than Princess. They do cater to, perhaps, a slightly older clientelle, but are family friendly. For the most part, most mainstream lines have become a less formal. I, personally, enjoyed the formal evenings being formal, but I guess that was outnumbered by those who don't.
I think HAL has excellent service and their ships are immaculate. Best wishes and enjoy your cruise!
