i dont think it's surprising that the resort is starting to quieten down, a few years back it was getting to bursting point after all the press it got and people flooding to it.
I went in 2001 (which was the year they filmed club reps there) and boy was it busy... and by that i mean every single bar was flooding out into the street.. down bar street was like a carnival atmosphere it was that busy, you couldnt move. We had one of the best holidays ever and im so glad i went at that time.
On the other hand i wouldnt worry about the place not being busy, yes it might not be at its peak anymore but im sure you'll still have a great time. For example i went to Gumbet (Turkey) in 2004 and people on this forum told me that i few years prior it had been mad busy with 18-30's but had gone quieter now. They were of course right (the information on this forum is second to none) but the main bars on the bar street still got busy and we had a great holiday.
dont worry and look forward to it
