I have attended two of the Big Smoke events, one in Dallas, and one in Vegas. Actually navigating to each of the booths and collecting all of your cigars is a bit of a hassle. However, the event as a whole is fantastic. Relative to pricing on Cigarbid, the $150 admission doesn't seem like such a great deal for 25+ cigars. But, for the entire evening, you can eat and drink your fill of a wide array of premium spirits(primarily scotch and bourbon) as well as wine and beer, and have all the food you like from the various restaurants that take part in the event.
It's a party atmosphere, and I personally would highly recommend the experience to anyone who enjoys cigars. I took a client who doesn't even smoke to Big Smoke Dallas last year, and he had a great time just sampling all of the premium spirits, listening to the bands performing, and eating the great food they were serving. Say what you will about Cigar Aficionado Magazine, but the Big Smoke is great.
