Modern RV sites have GFCI. They have no/few GFCI trip problems. Amperage has nothing to do with leakage current trips (GFCI). And if you have ever seen an RV campground (go to Yellowstone some time) you would realize your statement about less cycles is purely made up. Hotel car charging locations are typically empty when compared. Your whole fear factor GFCI stuff is bull and you just don't know it. Modern hospital switch gear has GFCI built into the MIAN disconnect. Hospitals draw lots of amps and do not trip out power from nuance trips.
It was my understanding that all EVSE systems already have GFCI built into them or I should say the equivalent. "they use a charge circuit interrupting device (CCID) to stop any leakage of electricity." (One example is linked below) You will get the same nuisance trips as modern day GFCIs.
In either case if equipment is taken care of properly it will not be an issue with a portable or hardwired EVSE. Hardwired is for higher amperage.
I remember the hard wired EVSE's (chargepoint) at the local university where I lived often had problems with similar GFCI type problems except it's would technically be called CCID problems because they had rental electric vehicles charging at the spots and the people that rented them would just unplug and drop the cord on the ground. They'd get saturated inside the port on rainy days and trip out inside the EVSE at next use. Same as with any GFCI. If a person brings their own $500 UMC they will take care of it better. Then there is also the failures from the cords getting run over, constantly. Again when someone brings their own it will get taken care of.
Your arrangement for hotels to use hardwired EVSE systems is from an industry point of view that wants to make extra money selling a BOX that does nothing but turn on a relay to provide 240 volts to the car because the car has the chargers inside. I would say it's a fantastic idea except for the price being charged for these switch boxes. No hotel, parking garage or apartment wants to spend that kind of money. I know I just installed 14-50s at a local apartment building that thought the price for an EVSE was outrageous compared to a GFCI'd plug. Plus the apartment LOVES the idea of not having to provide the maintenance for the EVSE because that belongs to the customer.
