Haha I'm glad someone out there appreciated the Dumb & Dumber reference...
It's getting warm over here in the States and I'm getting that spring feeling. Only a matter of time till the ladies are out tanning. (Sadly I don't live in Cali or Florida!)
Good thread and I'm glad someone started it! Seriously though, you make a great point about the week of running of the bulls and how it relates to the guy/girl ratio in vacation hotspots. I learned this lesson long ago in Cancun on Spring Break. One lesson: Whatever bar the hotel/resort is promoting that night for drink specials, free cover, etc, run in the opposite direction! It's bound to be flooded with dudes all full of the same misconception, ie "This place is gonna be MOBBED tonight!" Yeah. Mobbed with dudes. Oftentimes, the "place to be" in vacation hotspots is the exact opposite when looking to pick up! Your best bet is to just pick another club (there are probably dozens) that's central but isn't getting hyped by every resort as the "place to be."
As for Nice, how did you find it midweek? It's been a few years since I was there but I recall partying hard every night and we ended up with couple fine southern ladies from Georgia

Fellow travelers are always ripe for the picking. We mainly hit bars instead of clubs/discotheques but had a productive few days. Good times.
