Ukran1ans....I'm not sure what being Canadian has to do with it...eh?
Canadian Universities are on a break around the time you've mentioned...but it's definitely not like the very long ago Spring Break days.
In the years I've been living here (yes, I'm pulling that card)...February is without a doubt the busiest month with the beach being extra busy but not the street.
Now, the beginning of August has the most active week of the year and the street gets crazy packed in Negril!
