I have been coming to ISC West for 8 years at Sands Expo. It is a big convention bringing vendors and attendees from all over the world. The space is perfect and well laid out.
Getting your badge is a breeze due to the well organized event staff. Lines appear long but move really fast. The event staff and very friendly and helpful.
The location is also a huge plus. Being right next to the Palazzo and Venetian adds extra space for Vendors to hold meetings in a suite vice on the floor.
One of the better convention centers I have been too. Looking forward to ISC West 2015! V
