I have been coming to LV for over 20 years for different trade shows, conferences, and expos (plus shows in cities like Chicago, L.A., San Diego, San Antonio, New Orleans, etc. for comparison). Yes, the convention center may be confusing for a first time attendee because The Venetian (and subsequently The Palazzo) were build around it. It has been updated and compares favorably with convention spaces in other cities. Tips: don't eat the overpriced food in the expo area - go "upstairs" to "St. Mark's Square" and enjoy a nice lunch at one of the many very good restaurants or hit the food court for some quicker choices. Get coffee at The Coffee Bean. Wi-Fi is ridiculously priced so we use a phone or other device to create a mobile hotspot to access the internet. I have not had a problem with cellular reception. If you find the hotel prices too expensive, I've stayed across LV Blvd. at Treasure Island and use the pedestrian bridge to The Venetian or Harrah's (which has a LV monorail stop) and is next door (exit out the back near the parking area to make your way over to The Venetian). Enjoy your time in Las Vegas!
