ctctim, you'll be on CP69. CP68 are out here November 23rd, or there and thereabouts.
Gar, the taxi from Bournemouth to Dibden will cost around £30.
Ronnie, the insurers that CTC tell you about (they state sooo many times that they are not recommending - FSA rules or something) is Paul Jones Insurance Services Limited, PJIS. They are expensive, however, and I have heard of people getting significantly cheaper deals. However, this may be offset by the fact that, were something to go wrong, you are dealing with a company that is totally familiar with the scheme, making claims far simpler and more likely to be successful. Six of one, half dozen of the other.
