I'm going to Las Vegas

Finnally I'm travelling abroad. Next saturday I'll be in Las Vegas. Lolumo told me there's plenty of things to do, there're a lot of excursions and trips you can make, and also there's a lot of things to visit, to see or to enjoy. I'm really excited. It'll be my first time at the United States. I've been in Ingland, Ireland, Finland, Thailand, Greece... I can't remember all the places I've visited. But this time will be different.
I don't know exactly what will I do in Vegas. I suppose I'll visit the hotels, casinos and discos... But I also want to go to the Great Canyon and maybe to Los Angeles (it's 4 hours far from Vegas by car).
I promise I'll show you photos.
