There are some asterisks you've omitted. Most importantly, there are a few areas with CHAdeMO and/or CCS but no Supercharger coverage. Some Canadians gripe about this, since some parts of Canada fit this description. This type of problem is rare, but as
@Smitty79 hasn't shared a location or information on where s/he might travel, we can only guess about whether this would be important. Also, there are a few free CHAdeMO/CCS sites, but they're pretty rare.
As
@Smitty79 mentioned Electrify America, my guess is that s/he is in the USA; and of course, this is the North America sub-forum. In Europe, Model 3s are now being delivered with the European version of CCS plugs, so they're more inter-operable. That's still useful information for North Americans in case one runs across Euro-centric documentation that refers to plugging Model 3s into non-Tesla CCS DC fast chargers; that can't currently be done in North America (although CHAdeMO can work via a $450 adapter, as you've mentioned).
There's already a European adapter (at least, demonstrated; I don't know offhand if it's yet available for sale) for Model S and Model X, which don't have the full European CCS plug. This adapter is useless in North America, though, since both the CCS standard and the Tesla standard are different here than in Europe. Tesla has hinted that a North American version will eventually be available, but it could be a long wait, and I wouldn't rule out the possibility that it will never materialize. The wait is likely to be long enough that I wouldn't care to make predictions about Supercharger vs. CCS charging by the time the adapter is released.
This is a feature of the
PlugShare Web site, but it's not yet available on the Android or iOS apps, AFAIK. On the Web site, you can filter by amenities, which include lodging.
