This is a three day weekend at Caerhafod Lodge, Llanrhian, near St Davids, Pembrokeshire.  So the costs are a little higher, if you want to book the extra night.

For those who are not used to Streetmap, the little white bars on the right hand side of the display allow you to access a variety of maps, from Bartholomew's to Ordinance Survey to street names. Also, the "click here", written very small at the bottom, identifies the location of the arrow in too many ways to mention.
