Don't blame your camper...
We just left there Saturday Morning after 8 days. St Andrews is notorious for low voltage during high demand. They upgraded a few sites in 2010 to 100 amp service but the volt meters show, the supply is still insufficient. We saw a low of 105 volts every day during peek heat and up to 118 volts when the rain moved through. Late at night, we could see 120 YAH!
This park has been left unmaintained for several years. The same pot holes and standing water you went through were there in 2009. They call themselves fixing the problem by dumping a few loads of limestone in the holes, they are back after the next rain. So much rain is their excuse but the rest of Panama City Beach is well groomed and no water standing. I send a letter to all my State Legislators and the Governor after each visit.
