Helicopter Glacier Landing in Denali or Juneau???

[heelfan]

Hi Everyone,
I hope you can help me with an excursion decision. We are going on a cruise tour with Princess in August that includes 2 nights Fairbanks, 2 nights in Denali and the southbound cruise to Vancouver. We want to do a helicopter Glacier Landing and there are 2 options for location. One would be to do the "Denali Glacier Landing by Helicopter" out of the Denali Princesss Lodge which lands on the Yanert Glacier or the Juneau options which include" Mendenhall Glacier helicopter tour", Four Glacier adventure by helicopter, or "Helicopter Glacier walkabout". I guess the big question is which is more likely to have the best weather. Since it seems that Mt McKinley is in clouds or fog most of the time would that effect the views doing the glacier landing in Denali? Has anyone done any of the tours? What is your opinion? Sorry about such a long question but this is our first trip to Alaska and want to get the very most out of it.
Thanks
