rivergrove campground in drumheller ??

Just curious if they're opening this year. I've have the May long weekend reserved there. (had to book & pay a yr in advance). Been trying to get ahold of them for a few weeks. I would just like to confirm reservation. Website says the phone line is turned on in mid April, but it's still not on. No email available thru website.
Last resoort, we'll camp at Walmart. (Now THAT'S camping) ;-)
