We have stayed in the Iron Horse many times over the last two decades to ski Winter Park, but will likely not be going back soon after this next trip. They used to run their own reservations. Now they have Apline Resort Properties (on the website) / Allegiant Management LLC (on the Visa statement) doing it and they play pricing games worse than the airlines.
You are supposed to get better prices reserving in advance. When I called in late Nov 2010 to book two trips - one for Dec 11-18 2011 and one for Jan 29-Feb 5 2011. On the first , they had a special "late booking" deal - $59/night. For the second, they quoted $298.50 / night. for a 2-bedroom - over 2 months in advance. This was supposedly a "special deal with a big discount - for booking two trips at the same time and for having stayed there many times in the past. I took it though (what a fool!). It was all marketing BS. It is now Jan 11 and this morning, the price for anyone on the internet was $275/night - before a 20% discount. Tonight, it is$551/night - for the same type of unit, on the same floor in the same building.
If booking through Alpine Resort Gougers, do it as late as possible - and DEMAND a *MAJOR* discount from anything they quote (sale or otherwise). Adding in taxes and fees, our 2-bedroom condo is costing us $340/night. It should probably be about $200-240.
The untis themselves are quite variable, but typically worn and dated. The last one we stayed in (Dec 2010) was dark as a tomb even with all the lights on, the bed was seriously uncomfortable and there were very few dishes. The ski-in/out access is iffy at best. To ski out, you have to pole down Corridor to WP base. To ski in, you either have to ski down Mary Jane late in the day (usually black and icy at the top, but OK half-way down) or walk uphill 100 yards or so at May Jane base. You can also ski down Lower Arrowhead loop, but the Pony Express lift is almost never open these days, so you can;t get to it without skiing seriious blacks fromt he top of MJ.
The Zeyphr is *WAY* better these days - and significantly less expensive. The Iron Horse used to be one of our favorites, but is surviving strictly on (past) reputation now. If shuttling or driving is OK, then there are a lot of better AND far cheaper places in the area.
