Just a note to say that if you are planning a trip to Centerparcs in either Nottingham or Penrith – the O2 network coverage is very weak. Also had issues with very slow Internet access on the internal wifi network. You could use dialup connections if all else fails. In fact I did that on a previous visit and it felt surprising fast.
It’s pretty startling how bad mobile coverage can be and this when companies are planning the next generation networks.
