Ally sounds like a good trip.
Sorry can’t really think of staying recommendations, you are choosing one of the most expensive parts of GB. (Having said that Brighton is FUN).
Perhaps the best for travel would be Pyecombe where Longhurst kept the bar jolly.
http://www.pyecombegolfclub.com/history.htmlHas a solid but not inspired local reputation.
A bit better thought of is Crowborough Beacon

You can probably get a stay and play deal at
http://www.eastsussexnational.co.uk/golf/about/I predict 15 will love it and one of the group will be shaking his head saying that’s the last time I listen to Muldoon…or maybe not.
Another place with a Dormy house
http://www.seafordgolfclub.co.uk/contact_us/ I’m sure you’ve considered these, but a bit of a detour might allow for
Hayling Island (I know you have a thing for Old Aristo’s in Beret’s)
http://www.haylinggolf.co.uk/home/ Chichester is a lovely area (if expensive) and Bosham should not be missed.
Tandrige is not million miles away?
Riegate heath has changed the 7&8th since Tom Doak said they spoilt it’s chances of being a contender for best 9 holer. There are two sets of tees for most holes so it shouldn’t feel like one.
The Addington? Prediction. 1 will absolutely love it and some of the others will be saying this is the last trip Ally gets to organise….
Enjoy
