Whistler or Beaver Creek?

Next year I've got late Easter off & looking to go to Whistler for 10 days in the first week of the Easter hols which are at the start of April.

There are a group of 10 or so going.
One is set on Whistler & another adamant that it's late in the season for Whistler and we should go to Beaver Creek. The altitude of Beaver Creek may be an issue for one of the party who has heart disease?

Is the start of April likely to be too warm & wet in Whistler?

Andy, these two sites might give an interesting comparison. If you accept that all northern hemisphere resorts have snow melts during April, the question is one of degree. So look at the slope of the graph from March to April.
I have skied and enjoyed both places, but not in April!

Thanks Dave - looks like the thaw starts earlier in Beaver Creek than Whistler.
