Anyone ever attend a Cannes Lions School Academy? or a course at Hyper Island?

I've been given the opportunity to do one or the other. With Cannes I have a (possibly once in a lifetime) opportunity to go to Cannes. I would go for the Marketer or Account Leadership Academy and have access to everything during the festival. With Hyper Island I would get to pick any course and attend for a few days.

Feels like Cannes is the better option here but just wanted to see if any one has ever gone or knows anyone that has? Unfortunately I cant find much about either online... especially not the Cannes Academy. I just want the sweeter opportunity- someone tell me!
