Hi Peter,
Where is this OLD town of which you speak? Have I picked the best station?

Ok so dinner is sorted. Looks as though I will arrive at the Portsmouth & Southsea station at 1 PM so what to do for 6 hours remains the question

Always travel with a good book and a towel

Moose,
the old town is very nice this time of year, great place to watch the boats come and go through the harbour, just over the water is HMS Dolphin and the Submarine museum.
Just keep clear of the red light district, there'll have your wallet cleared out in no time.
