If you were on a tight budget you could have quite a nice trip along the same coastline without playing any of the more famous named courses mentioned - West Cornwall, Newquay, Trevose, Bude, Minehead, Weston s-m, Clevedon, Swansea Bay, Langland Bay, Clyne(?), Machynys, Ashburnham, Tenby. Not saying all of these are in the class of any of those mentioned earlier but there's pretty decent golf to be found if you look for it, and as mentioned on another current thread, even lessor courses are likely to have some merit.
