Hi Craig,
I visited Banff, Jasper and Lake Louise in January of this year on JY’s ‘Winter Rockies Spectacular’ tour. You can find my review in the appropriate section of this forum, which details my experience and also has some tips for visiting the Rockies in winter. Suffice to say that this was a fabulous tour, my only ‘complaint’ being that I had to come home! How I, and everyone else on that tour, would have loved to have stayed for a few more days! The Rockies in winter are truly spectacular, majestic, magnificent...humbling even, so go ahead and book. You won’t regret it.
If you’re also considering a visit to Africa, I can recommend South Africa and Nambia. I visited Nambia with JY in August of this year - again, you’ll find my review of that holiday in the Reviews section of this forum.
Welcome to the world of JY travel; I hope you enjoy it as much as I have. And if you have any questions, just ask.
Cheers
Mike
