I booked a cruise with them for 8 people last month. So far my experience has been very positive. The TA we booked our March cruise on the NCL Spirit with was not responding to emails and had not sent me the information I had previously requested from her more than twice.
An added bonus was we were able to get a great group rate through Crucon.
I dealt with a gentleman named Neil and he was very thorough. I was able to get two doubles for less than what I would have paid otherwise for one quad, and will get a total of $200 shipboard credit, a cocktail reception for our group and some other misc. trinkets and such. So I have to say I am veyr happy with them right now.
What date are you going in Sept? I have used Crucon a few times, and have had no problems at all, I had neil once before also, but was told he had left, very nice, but maybe it is a new neil I just had my friend book a cruise in september with crucon , the price went way up and they had a one day sale ,and I told my friend to call and book, now she is going to go with us, Very good service they provide.
