Thanks all.
I'm staying by Queensway now. The bike in box is stored in Waterloo now. I can get anywhere with the tube easily.
It's a suitcase sized box since the bike has couplers to break it apart. The box is 61 cm x 61 cm x 26 cm.

I'm not sure how long I will be going, probably around 12 days. My plan is to go to Stonehenge on Tuesday for the solstice. Maybe without the bike to make logistics easier.
I would like to take a train to Land's End and start riding north. Eventually I would like to ride through Wales and Scotland but I will probably have to come back another time to complete the journey. I could probably get as far as Bristol this time. The guidebook I have, Lonely Planet Cycling Britain (1st ed from 2000ish), breaks the days up into about 100 km. That's an enjoyable pace. About 20 days to John O'Groats, but without visiting Wales. I may stop earlier to have more time visit friends in France and potentially catch the TdF early stages in Brittany.
The train station storage is also possible if I'm not able to connect with anyone here. I would be happy to buy some beers and share cycling stories.
Any comments are appreciated. I don't know about taking bikes on trains towards Stonehenge or Land's End for example. I am planning to ask at the train station.
Thanks.
