Oliver, I’ll mostly second what Bill has said here. However, I encourage you to actually consider a /48 per guest room as well as a /48 per hotel for the hotel itself. Yes, this is excessive, but IPv6 was designed with these types of excesses in mind. We don’t yet know the scope and breadth of what will come out of IoT development, but one thing we do know for sure… Development tends to get stymied by whatever turns into the lowest common denominator among available technologies out there, so if 10 hotel chains give their guests /48s and 2 give out /60s and one gives out /64s, development may well lock everyone into nothing better than what can be done with a /64 even if better is available. We’ve seen this time and again with products that depend on autodiscovery processes that rely on everything being on the same LAN and assume that they can just trust the NAT router to protect that LAN from anything else. This is clearly a very bad strategy to anyone who understands networking, yet if you walk into your local Best Buy, more of the “internet enabled” products on the shelf have this behavior than don’t… Far more.

Hotels are both simple and complicated. There is a mix of our staff and equipment, guests and their equipment, and brands with their equipment. But really it's just one operating entity that ultimayely isn't that much different than any other enterprise out there. Now multiply that by 60-65 sites spread across the country and we need to manage our 6000 staff and networks accordingly. We operate 100% of the hotel, top to bottom, not just the technology. I wouldn't want ARIN or anyone else thinking we were an ISP if we aren't. Particulary if that creates problems in the future as rules (and possibly costs) change. However, if what you are saying is that registerong as an ISP is actually the correct way to go about this in ARIN's eyes as well, then that's a different story. Thanks for the tip on IoT sizing. That's precisely the kind of thing i am concerned about being constrained with in the future if we size sites too small.

You're trying to be an ISP under the end-user rules. However transient, your users are mostly customers rather than staff. Just register as an ISP and get the default /32. IIRC, ARIN sparsely allocates IPv6 so if you go back for more addresses there is a high probability they'll just increase your netmask. Finally, /56 or /60 per guest, not /64. IPv6 can do nifty IoT things like collecting all of a guest's devices behind his personal firewall but it doesn't work if you've only assigned a /64.
