My guess is the geeks are working furiously to integrate systems and deploy RFID.
Icon will be direct to lift RFID at a bunch of Alterra and Powdr resorts. Copper added RFID this year, so RMSP+ RFID worked at Steamboat, Copper and WP. I heard Powdr is adding RFID at Killington. Not sure about Eldora. Note Ikon is managed by the same folks at Alterra that have been managing the RMSP+ for years.
I think the big question is all the non Alterra and Powdr resorts like Aspen, Jackson, and Snowbird that already have RFID. Will they get those systems integrated into the Ikon mothership at Alterra before next season? We'll see.
At Crested Butte you had to walk into Guest Services and get a ticket with RMSP+. Given the likely Ikon Pass volume, resorts are going to try to avoid that if possible.
