You can get cheap lift tickets at www.maisondeski.com (in Idaho Springs on the way to Breck off I70) or www.sitzmark.com (travel co offers cheaper lift tickets out KS). ABasin Super Bonus Pass at $219 is always a best bet but I am not sure if they are still selling them. Have fun!
Attacking Mid---the "ski with a friend" rate that passholders get for friends has really gone down the tubes---I don't know why they still even have that program. The other discounts you mentioned are a better deal and anyone can get them.
geezer---go to www.snow.com and get the phone number for their information line (Vail's--not Breck's).....call and ask if they still have the 4-pack deal available or for any other options---they will be glad to tell you what's available.
It is a busy peak period week (Spring Break) so it may be tough to find a really good deal. Good Luck !
I had 3 more ski with a friend discounts left on my Colorado Card and we used them at Beaver Creek last Sat. and they were only good for $10 off the $77 lift ticket, Back in Dec. when the daily rate was raised to $77 at Vail the ski with a friend rate was $55.
Vail Associates worse than the airlines with different rates at different times.
