Illycon 2021

I would love to be able to make it for the Illycon 2021 in the USA. Which state or town is up to you guys, you know them best :)  Make it a good one - I'll try be there!!

All things considered I feel that Orlando is a much better choice.
For once (as already mentioned) there's no guarantee that everyone will be 21 or older, which will significantly restrict activities and events that fellow Illyrians will be able to participate in.
Additionally, Las Vegas costs a whole lot more than Orlando. I vaguely recall my father griping about 20-25$ for 1 beer in vegas. I can go to just about any bar and spend 4$ in comparison. Even if the flight is more expensive, odds are that you'll save much more with everything else, or at the very least break even.
Also, Orlando has multiple attractions that Illyrians can visit, and enjoy whereas Vegas is... well... vegas. It's a giant money making machine. Orlando is more down-to-earth and (in my less than humble opinion) pleasant.
