As long as the 50 amp RV does not require both A/C's to stay cool in the hot summer months you'll be OK. 50 amps sort of makes you lazy because it allows you to run just about anything you want without fear of blowing breakers. Both A/C's microwave, and water heater no issues. To some degree you can get spoiled by 50 amps. You come accustomed to having all the power you need.
However 30 amp sites will still do the job if you practice some energy management.
However on a really hot day when you need both A/C's 30 amp sites will leave you a bit hotter than you want to be.
I have a 50 amp RV and try to use 50 amp sites as much as possible. In a pinch or if nothing else is available I will reluctantly stay at a 30 amp site.
Yes the convenience/power of the 50 amp pedestal has changed our destinations
