length of 30 amp line
How long can a 30 amp line from pole to RV be?

If this is a rare occurrence at one of the CGs you happen to visit, 2 x 30 amp 25' shore power cords will likely work if you monitor the voltage and restrict the load as needed and providing the voltage at the pedestal isn't too low. If you want the most power possible at a CG and want to get the volts up, get a Hughes autoformer to boost the voltage.
An EMS is a really good idea to protect your appliances and components and is highly recommended - Progressive Industries makes the better one. A PI EMS will automatically shut you down at 104 volts and the Surge Guard at 102. 102 is too low IMO.
The NEC and NFPA specifies where a pedestal is to be located on a site in an RV park and the NEC also specs where the point of entrance of a power cord is to be on an RV. You shouldn't normally need more than 25' of cord. Have run across 2 of them so far where the pedestal was at the front of the site. We carry a spare (detachable) 30 amp cord and have a generator adapter that allows 2 shore power cords to be plugged in together for 50'.
The CEC (Canadian) in the past has not specified where a pedestal should be located or where a power cord should exit an RV. There was a proposed amendment to the 2012 edition to harmonize pedestal location with the NEC. It doesn't look like it made it into the '12 edition tho.
If you get around to enough CGs, you will find that low voltage is a common problem with CG wiring, esp. in the summer with a lot of AC units running. An EMS and autoformer are a very good investment. A plug in or hardwired voltage monitor inside is a very good idea at a minimum. I installed both a hardwired AC voltmeter and ammeter (plus have an EMS and autoformer).
