I know Malta is a 'real' holiday destination but right up until CV took hold they held 4 full weekend sports tournaments in mid-April to mid-May from the mid-90s onwards; rugby, swimming, footie and beach volleyball (if I recall correctly). The Maltese Tourist Authority offered a flat EUR6/person/bed night in approved accommodation to each organising committee of the events all managed by about 10 approved travel agents who found the accommodation for the participants. I can't really remember how it was controlled but I think all participants had to be pre-registered and have return travel boat or air tickets for at least the length of time the tournament was run for.
I was helping out in a clubhouse bar one year but I heard Maltese Rugby Union turned in around EUR10K from the government scheme for their weekend. Teams from France, UK, Ireland, Italy and even USA turned up. It was probably one of the best 7 & 15 a-side tournaments I have ever attended. The Maltese Government didn't have to lift a finger but hotels packed, flights fully booked, restaurants & cafes full, nightclubs booming, sight seeing, boat trips etc, etc. And a good time was had by all.
ETA: Forgot to add that I passed all the scheme info over to Mr Corkish who was the Member for Tourism at the time but nowt was done about it.
