For this specific question, it sounds like you are asking about the Tesla Supercharger station that happens to be located at a Holiday Inn Express. That is not something that is owned or controlled by the hotel. Tesla's Supercharger stations are for Tesla car owners to use at any time, without any need for any permission from the business or site whose parking lot it is.
It sounds like you don't have your car yet, because if you did, you would find that this is far simpler than you are thinking of and doesn't need any pre-planning if you are on normal interstate highways, which are pretty much covered by Tesla's Superchargers (no adapters needed). You can just set your final destination in the navigation, and it will plot the route, including all charging stops and time at each charging stop.
All of the Supercharger locations are built into the car's map, but if you want to browse around any of this stuff from a computer, here are a few things I look at in a basic order of thinking about a trip:
1.
www.supercharge.info This is a really good user-maintained map that sources its data from this forum. It's got all of the existing Superchargers, plus places marked where people have discovered building permits filed or construction started for coming soon ones. If I look at where I'm going on the map, and the interstates already have Superchargers, then it's covered, and I'm done planning. I'll just play it by ear in the car as I go.
2. If I'm having to drive somewhere that's not just an obvious straight shot on an interstate, and has to take some smaller U.S. highways or state routes, those are not always covered as well, so I may need to check some of those gaps to see if they are crossable.
www.abetterrouteplanner.com
www.evtripplanner.com
Those two sites do about the same thing, letting you pick which vehicle, and some parameters, like temperature, etc. and it will plot a route to let you know how much energy it will use, and you can see if that will work or if you need to find other charging points in between.
3. If you do need to find other charging resources then,
www.plugshare.com is about the most complete site I know if for all kinds of charging resources. You can filter by plug type, and the charging speeds are approximately like this:
CHAdeMO: This is about half the speed of Tesla's Superchargers. Your car DOES NOT come with an adapter for this, but you can buy one from Tesla if you want for $450. Probably not worth bothering with if you can stick to interstates most of the time.
J1772: This kind of charging is about one tenth as fast as a Supercharger, so like a few hours kind of thing and so probably not something you want to have to use. The adapter for this plug is included with the car.
And that's about as extensive as you would need to get. Those tools like ABetterRoutePlanner and EVTripPlanner can plan full routes using Superchargers like the car does, so they are interesting to play with just to see how easy it is to go places.
