I am planning to spend 8 nights based in Amsterdam. Yesterday I received an email from TripKey that their service will be unavailable for an indefinite amount of time and I was referred to the Utrecht Regional Pass which is described as being "powered" by TripKey.
https://utrechtregionpass.com/faq/ It seems to provide the same services as TripKey. I am not sure if this is just a re-branding of TripKey, a merger with TripKey or an independent service using TripKey's technology. I could not find any reviews of the Utrecht Regional Pass. Has anyone used this pass for transpiration and/or direct me to reviews of the Utrech Regional Pass?
