Pembrey is quite a large site with 125 Pitches of which 68 are hard standing. Mobile Phone signal was OK. Digital TV via our Omnidirectional Arial (flying saucer type) was iffy. Site has WiFi but as with all Caravan Club sites it is Slow.
There is only 1 Toilet/Shower Block which requires a Key for Entry, the Keys are supplied by the warden once you have chosen your pitch. You also get a 'Fob' for the Entry and Exit Barriers.
The site is quite a way out of town, I didn't see any Bus Stops so if you have a Motorhomer alternate transport is required. There are miles of walks and Cycles ways to explore and the Beach (Blue Flag) is a pleasant 20-30 minute walk away.
Some of the Pitches may be prone to flooding after prolonged rain (49,50,51 area). And the Grass pitches looked rather soggy.
