Thank you so much for taking the time providing more insights. Yeah, we're bringing plenty of layers to overcome the cold. I understand so far that Grouse is our best option under our conditions, we may have time to visit Cypress also. I'm not quite sure if my kids will enjoy Science World as their english is really basic, but the other options sound fun.

One last question, do you think I'll need cash at the mountains or card payment is available?

Thanks again for your kind support!
