If they have an Alaskan area in Las Vegas during the summertime and keep it really cold, you know there will be a lot of visitors those buildings.
And yes, I would visit an attraction of Alaska in Vegas whenever I visit again.
I think that having an Alaskan Adventure Center is a good idea and would probably be a hit if they have a big area or room that's kept cold during the summer...
Something like; the Alaskan Climate room, where people can experience the cold temperatures of Alaska.
Like either two or four different rooms, one for summer and winter or one for each of the seasons.
Then, charge a fee for a coat rental so you could visit the colder rooms.
It's just an idea that popped up in my head. If they show an exhibit of the annual dog sled race it could be in the coldest room, to give people an idea of how cold it is when they race the dogs.
Overall I like the idea of the Alaskan Aventure Center in Vegas.
