(Nullth, "a service that just works" is a notoriously tricky goal, in any case; and indeed most things suck) First, IPv4 address pool has been depleted for some time, hence the NAT (there are more IPv4 devices than public IPv4 addresses, yada yada, you know the drill). Second, IPv6 support in COTS computing devices is (still!) spotty. Third, "just works" means very different things - for watching lolcat videos and browsing Facebook, NATed IPv4 is pretty close to "just works" for an average Joe with a laptop; obviously not for more demanding customers. Fourth, this is a market niche that's been refined for a decade - and hotels are not usually in the "early adopter" bracket, more in the "the net connection doesn't need to be very good, but it needs to kinda-work for everybody" category.
