Replying to Skiing Whistler in June

Headed out to Vancouver on a family trip two weeks from now, and was gonna head up to Whistler for some biking/ glacier skiing for a couple days and wanted to see if any of you guys knew what the public park on the glacier and skiing in general is like at this time of year. COC can sell me a park day pass which is kind of expensive but can get me more access and more hours of skiing but I am trying to figure out what I am best off doing. Thanks
