Aged,
May would certainly be no problem here weather wise. Like everywhere else, we get systems coming through, but typically, the weather's pretty good by then. Even April is pretty good; has been our busiest month in years past! Floatplane will be in the water by the end of March, possibly sooner.
Absolutely love to rent the plane upon completion of a Mountain Course. You will need a license Validation Certificate, but we can deal with that as the time gets a bit closer.
Take a look at the website, and see if any of the accomodation or other adventures tickle your fancy. We can make any arrangements you would like. Our goal is to be a full service aviation destination. Ainsworth Hot Springs is 30 minute drive away, great place to soak away the rest of the world.
Here's a little teaser:
Hope to speak with you soon.
Merry Christmas everyone!
