Can we get a consensus on the difference between these if any? Wikipedia says they the same thing however in my mind there is a clear distinction between:
Colo company offering cabinet space, floor space and dedicated servers in their IDC.
vs Company that owns large buildings and rents out redundant power and floor space (littler or no IP services). And of course attracts carrier aggregation to the building
When looking at the vendor neutral carrier model, a hotel makes more sense seeing as the managing company is not selling "IP" services and hence competing with its clients.
There really isn't much difference in the terms, they are often use interchangeably.
Your term about the IP part is somewhat correct. Carrier hotel often leases off large chunk of space to carrier and then the carrier operate the space as a datacenter. The carrier hotel, like Telehouse, does not operate an IP network and does not offer any services usually available from the "datacenter". In this case, the datacenter would be the party that will at least offer IP. Additional services such as management, security, equipment lease...etc., maybe offered.
The general trend is the people that classify themselves as a carrier hotel usually leases space out in big chunks, often floor by floor. On the otherhand, the people that offer datacenter services usually sell the space by the U or by the rack. IP is almost always a part of the offering as well.

"Coloshops have to purchase loops and do other gyrations to get packets directly to the facility."
Gyrations? We have not only two redundant fiber feeds into our facility, we are also one of the few data centers that has 500Mbps+ of licensed microwave into our site. How that is a gyration, I have no idea..
Generally the “Carrier Hotel “ is where Carriers are, as in your traditional TDM telecom companies. Typically these are larger operations that are necessary for voice carriers to exchange traffic, and usually the switches in these facilities will have their very own CLLI codes designating their Class 5 switches for example as a certain interchange for certain NPA and NXX on the PSTN. With the predominance of VoIP you do see a lot more IP/Datacom companies in these Carrier Hotels, but unless you really need to connect to someone there, and there is no other way to do it…it will almost always be more cost effective to use a Privately Owned Datacenter that caters to Enterprises, and IP Service Providers. The Carrier Hotels simply command two high of price per square foot, with no additional perks other than connectivity. These days, there are quite a few private data centers with excellent fiber connectivity to one of more carrier hotels, so you can often get all the connectivity, in less expensive real estate.
And although it’s been quite some time since I was colo’d anywhere, I’d have had more than a few bad experiences dealing with “building management” types in carrier hotels, much more so than you are likely to run into dealing with generally more technical professionals in a private data center.
The downside is that many of the private data centers are not as carrier-neutral, so you will have to do some shopping. You can easily pay through the nose for cross connects in one facility, and get the same connectivity with free cross connects in another. Typically they only have a few carriers to choose from, and when you buy Yipes, Level-3, Savvis, or etc. you may be buying it from the data center, off their switch, instead of getting your own direct connection. Although there are plenty of privately owned data centers leasing space in carrier hotels, that works, it’s just expensive. Although if you can afford it, pas the credit check, and you have a long term business model…actually doing the real estate lease and taking on real space in a carrier hotel is an option…and usually cheaper than colo’ing with another provider, but unless you need a lot of space and have the expertise to run your own data center, that can easily be costly in other areas beyond the rent and insurance.
A carrier hotel is not for your average small cage or customer with a few racks. They generally do not have such ammeties as remote hands, or technical people, or even licencing agreements to help you. Point being is that they are generally a little higher on the "food chain" as most colo shops.
And the trade off is of course is cost. I have suspected that some of the carrier neutral facilities were not so "neutral" afterall. I always felt that somehow there was somebody's hand in somebody else's back pocket.
I was at a major colocation shop, and nobody could ever provide me with a list of carriers in the building. They wanted to always sell their proprietary mix. Never yet have seen that list, or list of contacts.
And when I went above the facility, I actually was able to negoitate lower pricing that the shop could get themselves. And guess who they are running now as a provider in the mix.......
