I think you can get to London in less than two hours from there.
Why do you have to go directly from P&S? Petersfield also gives a good rang of destinations as does Cosham and The Hard is the end/start of lots as well..
In fact you can get directly to London Waterloo and then can go anywhere inLondon. Watch a show or something with a nice restaurant. We often go to The Travel Lodge in Woolich as it is very close to the underground.
Trains to Cardiff serve Salisbury (1:16), Bath (2:10)
Trains to Brighton (1:20)
Each of these routes serve other towns that may suit you.
With a simple change at Southampton you can reach Bournemouth (1:35)
hi cassa, it's 2 70 year olds who do not want to change trains. They could probably get to cosham just as easily, if there were some nicer destinations from there. London is out
My mum and dad are in their 70s and they always go to Warner adult only hotels. Mind you they live in Drayton and go in the car to get the ferry to the Isle of Wight and always stay at Bembridge Coast Hotel at least once a month. They are Creatures of habit but they enjoy it.
Probably not relevant, but to clarify an earlier post, you can no longer get from Portsmouth to Brighton on one 700 bus - you now have to change twice, at Chichester or Bognor then again at Littlehampton.
Splitting the 700 into three sections was done to "... improve the punctuality, reliability and frequency of this service".
