As mentioned in several posts, I get extremely car sick and tend to have a weak stomach so when I went to Breck in 2010 I was very anxious about getting Altitude sickness.
After reading suggestion and after suggestion what I did back in 2010 and will be doing this week is I am flying into Denver on Friday night. Saturday morning taking my time to get out to Breck, enjoying the beautiful drive etc...drinking plenty of water, not much alcohol on Saturday and getting "used" to the altitude. Plan on a good night sleep then kicking it Sunday.
For me it is worth it to not be on the slopes on Saturday to make sure that Sunday and Monday I feel good.
I can't wait :)
