I booked last minute on my phone; the location required that I print out the ticket. This was awkward & only successful because they had a computer and I remembered my SpotHero password. (I have it locked into my phone and try not to remember these things) This was the only fear/hiccup. I hope that there is a technology solution or one that involves developing your relationship with partner garages!
Great parking but wish I knew you had to go inside the hotel first to get your pass here going to their garage
