From what I can tell doing a quick look around the Internet is that the RFID industry figured out how to adapt to the fact that the use of pacemakers has become more common. Found a medical study from fifteen years ago when RFID readers were uncommon that found evidence of interference. The RFID Journal was well aware of that study.
Given how many seniors ski midweek and the increased implementation of RFID lift access, I find it hard to believe that people with pacemakers have a reason to be concerned.
Found the same caution for two completely different resorts (bold added). W-B is a huge destination resort. Gunstock imostly caters to locals in the Boston area. The text was probably provided by the RFID vendor. W-B explicitly notes they use SKIDATA. Axxess is the vendor used by more ski resorts in the USA. I'm guessing that's the company used by Gunstock. I've seen SKIDATA more often on the Pacific coast.

Q: What about RFID & Pacemakers?
A: RFID is the acronym for “radio frequency identification”. Devices many of us use everyday function with radio frequencies and electromagnetic fields, such as radio units, cordless or cell phones, or wireless networks. SKIDATA RFID readers are electronic devices that produce an electromagnetic field like any other electronic device used for hands-free technology. Based on SKIDATA’s own records, its research and its reports of independent research conducted on the influence of electromagnetic fields on medical implants such as pacemakers, there is no known health risk of interaction between SKIDATA RFID readers and pacemakers. However, if you wear a pacemaker, you should consult with your physician and refer to the manufacturer’s recommendations for your specific device, as you would with any electronic device. Out of an abundance of caution, we recommend that guests with pacemakers not wear the lift access media card near their heart when passing through RFID gates. We also recommend that guests not linger close to RFID readers, maintaining a distance of at least 8 to 12 inches from RFID readers while in line and when passing through the gate.
*If you wear a pacemaker or other medical implant and prefer not to pass through the RFID gate, please alert the validation staff at the lift and you will be given alternative direction for lift access.
