Hilary,

I wasn't on it but a friend took a cruise to alaska on Princess and he was able to contact the navigator and get updates daily as to when they would be passing by lighthouses.

He indicated that there was even a booklet available in the ship's store that listed which lights would be passed and aproximately where they were.

Tammy also posted this on one of my posts about the Europe trip-

"Dennis, did Celebrity tell you anything about the lighthouses? We've done one Celebrity and one Princess cruise. On the Princess cruise, they published approximate times we would be passing lighthouses in the daily newsletter, and the naturalist announced when we were going to pass one. "

Hope this helps.

Dennis
