We came here for the 2016 Comicon in Vegas. The con was one of the smallest ones my husband and his bff had ever seen (I don't know this was my first time) but the convention center was nice. Plenty of parking - a few places to eat (like Sabarro's pizza and a Nathan's hot dogs), a Fedex, ATMS, plenty of convention rooms for the breakouts, and the main convention area where the vendors were selling items.
We only saw one portion of the center as it had another hall/entrance but it seemed pretty nice overall and everything you're looking for when you're at a convention center! The Fedex was a nice touch because you can mail things you buy to yourself without even having to lug them out of the convention space! (Note: it wasn't open the day we were there tho' - bummer).
