I came back from Laganas on 20 July after being there for one excellent week. The nightlife was what made it as we found the restaurants were pretty un-appetising - apart from MacDonalds of course, although they don't do Sausage and Egg McMuffins! Bad Boys, Ghetto and Zeros Club were excellent. I particularly liked Cocktails and Dreams - which we nicknamed Cocks and Violations, as you were constantly getting felt up in there. I went back every night!
We stayed at the Savvas apartments which were pretty basic. The pool bar constantly played Heaven by DJ Sammy but that was eventually drowned out by the ear infections you get from the murky water. If you can hire a fan do so, coz it got up to 47 degrees while I was there.
When you are travelling back from Zante airport, wear comfy shoes and as little as possible, because you have to wait outside for nigh-on zillions of years in the 47 degree heat to check in and coz the airport is the size of a shoe-box there isn't anywhere to sit down.
I'd definately go back if you are looking for great nightlife. I went to Ibiza two months earlier and that was crap compared to Laganas if you ask me.
Quiet night on the balcony? Think you went to the wrong resort luv, Laganas definately ain't quiet - and thank god for that!
