I'm making a journey to Europe from Chesterfield (outward on 18th June to Brussels and return from Paris on 21st June). I intend to buy http://www.brfares.com/#faredetail?orig=CHD&dest=LNE&ldn=1&tkt=EVR for travel from CHD to STP. On the outward journey I understand the restriction about not arriving at STP prior to 10.10 but I'm confused by the reference to Eurostar off peak and the restriction code EU. I didn't think there was peak / off peak on Eurostar - I intend to buy a London - Brussels Eurostar single via the eurostar website and then buy the CHD - London International ticket to ensure that my UK travel is covered by CIV. Secondly, my return on 21st June coincides with engineering works between STP and Luton with a replacement coach service running. The train onwards from Luton to CHD is all stops and slow. NRE shows it quicker to travel Kings Cross - Grantham and then change there for the EMT NOR - LIV service through to CHD. I'd prefer to travel via Grantham than on a replacement coach. Does my Euro High Saver CIV (EU) permit me to travel via Grantham on my return? Any help and clarification greatly appreciated!
