The current electrical code has 7 50 amp, on ONE measly 200 amp breaker. Since 50 amp is "rv speak" each one of the 7 is actually 100 amps. The code relies on not all air conditioners starting at once.
So just two pedestals in heavy use may "max out" the 200 amp circuit, even if it is "looped".
The 200A breaker is a two-pole, 240V breaker, so it's 200A per leg--just as the 50A electric supply is 50A, 120/240V split phase, with 50A per leg. Two fully-utilized 50A connections would not max out the 200A circuit, but rather load it to half capacity. Whether the pedestals are installed in a ring or a spur topology is immaterial here.
The general point that the minimum requirements for RV park electrical installations are somewhat outdated and undersized is entirely valid. Adding EV charging to any great extent will exacerbate that in many parks unless significant infrastructure upgrades are also performed.
