Is it Dingley P2P you go to near Market H Aragorn?
Can fully recommend a trip to Whitfield (just East of Brackley) SC - great new course with full watering system and generally large fields - the two meets i've been to there in Feb have had 10 and 11 races.
Godstone this Sunday is probably your nearest SC - if you're in South London then Detling in Kent isn't too far to travel really (I'll be going there a week on Sunday if you're about).
The main issue is the declarations - you declare roughly 45 minutes before the race so there'll be a lot of tooing and frowing with connections to the decs tent to see who's entered in what and who is there to ride if you change race and the like or in some cases waiting to see if X hotpot fav is declared to run in the Maiden.
Pointing is like all racing SC - there are strong and weak areas, traditionally the South West/Cornwall is strong and an area like the North West is weak. Northern (ie. North Yorkshire and Scotland) is somewhere in between - a horse like QDP is from a very good yard who have plenty of success in points, and seem to be doing well with their young French-breds (Rapidolyte De Ladalka looked a decent maiden winner last season but hasn't really gone on). Chris Dawson rode QDP yesterday as his regular jockey Kelly Bryson was injured in a fall last Sunday at Overton - would expect she'll be back on board next time (injury permitting).
As for best courses quality wise you can't go far wrong with Larkhill (North of Salisbury) - as mentioned earlier Barber often runs his there, was there myself last month where he ran two nice winners in the two divisions of the Restricted race (Dualla Lord and Bucks Bond - the latter being a relative of Big Bucks).
If you're in the South East I recommend you follow Phil York and Nick Pearce as jockeys, Tom Ellis is another good SE jockey. Personally I don't think you can go too far wrong following the Andrews sisters either (Gina and Bridget) wherever they ride, particularly Bridget in Novice Riders races and Jack Quinlan is another good, young amateur. Tom Weston is another good amateur and then it's the usual suspects - Richard Burton, Richard Woolacott, John Mathias and the like.
Best refreshment I've had was at the Larkhill meeting where there were a couple serving hot, spiced apple juice which helped matters.
Cottenham is a nice course too - ex-rules with a small grandstand but basically most P2P tracks are fields with a few fences and railings in them. Godstone normally end up with small enough fields and yep you're right a lot of the crowd are on first name terms with the trainers and jockeys, it's easy enough to ask a trainer what he thinks of his in a race and the like (as always though you can never tell if he's telling you the truth or not!).
Any more questions etc. or if you're going to a meet then drop me a PM.

ps. the Jumping For Fun discussion forum is easily the best place for P2P chat.
