We are currently planning our west coast trip starting in Las vegas. We would be in vegas in the week of 29 march or the week of 6 april. The week of 29 march would be a lot cheaper to go since the trans atlantic flights are cheaper then. I noticed that the week of 29 March is spring break week for some schools in the US. Is it a good idea to go to vegas then? We are not exactly party people so it would not exactly be a plus for us to have it crowded with spring breakers. We are planning to stay at Aria. I'm from Europe so I don't have a good view on whether or not that has a big impact there.
