We just dined there in April (early) and they had the coconut races then. They've shortened their 'race track' from the last time we were there!! Didn't last long at all - and for the record, actually were no children in it above the ages of 5-6 that night.
Was a little apprehensive at first as our table was right beside it, but it was over so fast, and there were no issues with 'loose' coconuts or brooms!! LOL
It seemed way scaled down from when the 'lady' was directing it - not sure why.
