If Cinco de Mayo and college graduations weren’t enough, Memorial Day weekend presents the third official opportunity/excuse to party ridiculous in the month of May. Suggestions below:

FRIDAY (5/23) – Check out Friday Night Live at the Hard Rock Hotel pool, which kicks off at around 6 p.m. and features musical guest Stephen Marley. SpyOnVegas.com is also holding Open Bar from 6-9 p.m.. Friday Night Live is consistently one of the best spots to begin a summer weekend in Las Vegas. For a bit of a different vibe go downtown and find the Icehouse, which promotes Ink Fridays every Friday, and will also be the venue for the Girls Gone Wild search for the hottest girl in America. Cap off the night at Pure, with DJ Steve Aoki spinning and the Pussycat Dolls celebrating the release of a new single.

SATURDAY (5/24) – UFC 84 takes place at the MGM Grand, creating a slew of UFC after-parties. Check out Hawaiian Tropic Zone for an after-party hosted by UFC ring girl Arianny Celeste, or go to Studio 54 to experience Tito Ortiz’s official afterparty. Not to be outdone is the IFC, a rival organization to UFC. The First Annual IFC Celebrity Weekend goes off at Blush, with scheduled appearances by Carey Hart, Vin Diesel and Linkin Park frontman Chester Bennington. If you’re searching for a party not affiliated with Ultimate Fighting or its derivatives, check out Polly Esther’s, where Daisy from Rock of Love 2 is hosting the Bikini Bike Wash.

SUNDAY (5/25) – Rehab should be your No. 1 choice, but getting in won’t be easy. Sugar Ray is the musical guest at the Hard Rock pool. The Artisan, a favorite of Las Vegas locals, hosts the grand opening of its new pool party. Just about every Vegas pool party should be insane, so have a second choice ready in case you can’t get in at Rehab. Head back to the Hard Rock and check out Body English for Sunday School, but again, be prepared for long lines! Hanging out at the Hard Rock is usually an intense experience regardless of whether you get into the club or not.

It’s another great weekend to be in Vegas. Be sure to check out SpyOnVegas.com, as well as Las Vegas Weekly’s website for Xania’s Hot Spots, which breaks down just about everything going on that’s worth checking out for the entire week.
