Mike,
All and sundry will shitcan Trevose and tell you not to play there. If you are going to be in Padstow anyway, which you really should be because it's a great little town (you can get the ferry across the bay from Padstow to Rock then walk 5mins up the hill to play St Enodoc, adds a really cool element to the day - as opposed to driving 25mins to get to a spot a few hundred yards from where you started!), I would perhaps look into staying at Trevose (they have accommodation that looked pretty good) and play the front nine.
The back nine at Trevose is pretty bland, but the front is one of the best nines I have played in the UK.
If you're adding lifestyle to the golf, you must visit St Ives. It is one of the best places I have been in the world (and West Cornwall GC is just out of town).
Mrs W, if she'll be in London then for work, can get a £20-40 flight to Newquay from London City or Gatwick with Air Southwest to join up with you, and you can take her to the Porthminster Cafe in St Ives, which is all-world food in an all-world location, to regain some of the brownie points you'll be cashing in to play all that golf that week!
If you have any questions I might be able to answer, shoot me a PM.
cheers,
Scott
