I would call and ask, some former members of the crew work there as guides. In my opinion, you should be admitted at no cost in gratitude for your husband's service.
Probably so. I don't work there. But I bet you were allowed to go for free
I don't honestly know, but if you show them that info, I bet you get in for free. Just my opinion.
I think so, but you need to phone or email them.
Call and see what they say.
Best will be call and ask the crew members
Call and ask they are very nice people that are all volunteers and Sorry for your Loss
