Hi Nick,
This is my first InstructureCon as well so I appreciate your question. However, I am a veteran of visiting Las Vegas and can give you advice on how to prepare for that. As others have suggested, bring comfortable shoes! If you plan to explore the Strip, be prepared to literally walk miles. This is because you can't just cross the street to get to another casino - you have to find the nearest crosswalk or bridge to get to the other side, then you often have to use stairs, escalators or elevators to get back down to the street level. Last year my husband and I spent 2 hours lost in the Venetian trying to figure out how to get to the Sphere! Also, the convention center is huge! In terms of leisure time - bring a swimsuit if you want to check out the beautiful pools, sunscreen and/or a hat if you plan to walk outside, and some spending money. There are amazing restaurants but they are quite pricey. I love Las Vegas - where else can you go to be in New York, Egypt, Paris, Rome, Italy and the Caribbean all in one day?!
