Never ever give these guys your personal information! They will never stop contacting you despite multiple attempts to unsubscribe from their mailing list.
It's been over 5 years now and while I enjoyed the tour I took long ago I'm not interested in going again and I just wish Mark would appreciate that and leave me alone now.
I've gone form someone who recommended the tour to someone who warns people to stay away, the only scary thing about it is how they blatantly abuse you contact information.
