I feel I should contribute to tag wikis as to other aspects of TSE (and find tags with no wiki very unhelpful) but have had unfortunate experiences with these elsewhere on SE. So thought I'd try and offer a few suggestions while still requiring review from others.
If by Ohio River you mean flows into Mississippi River I think not an issue since I'd consider say North End, Croydon as a "high street" even though part of the main shopping area of Croydon is called High Street. "usually" is deliberately 'weasely'! I would be very happy for others to suggest corrections/improvements and my efforts were as much as anything to trigger some kind of response, on the basis that no tag wiki is worse than anything that is a reasonable stab.
@JoErNanO I've tampered with it (don't hesitate to roll back). I thought a map might be useful because of the scope for confusion over the names in different languages and Midi meaning South. Re-ordered N/C/S as 'conventional'. Added locker sizes at Centraal.

The accepted answer addresses check-in staff. I see offering them two passports no real issue - for example if I offer a card that was not the one used to buy the ticket they are likely merely to ask me for the right card. So I suspect only immigration officials are really relevant and for that I think a specific answer is possible. In which case, though expressed rather like a matter of opinion (I have no issue with the Q being closed) I think a specific answer (eg as I offered!) is possible.
The context is dual citizenship (not two passports from one country) and the premise (China is exceptional) is wrong. Take into consideration allowing/disallowing is about 50/50 then lots of question on the topic can be expected (without the canonical!).
@GayotFow Yes: When in doubt, can't you just show two passports?
@GayotFow I do not follow the news enough to know where the problems are in the UK, and I think the Dunkirk ferry might land near the Calais ferries, maybe near enough to be out of use when there are problems in England.
If you have driving a long distance you might like an overnight ferry that allows enough time for a proper night of sleep. On the other hand, if you can not sleep on a ferry you might prefer the shortest crossing.
Many phenomena - wars, plagues, sudden audits - have been advanced as evidence for the hidden hand of Satan in the affairs of Man, but whenever students of demonology get together the M25 London orbital motorway is generally agreed to be among the top contenders for exhibit A.
Modern parties at home where everybody is looking at some kind of screen, often each a different one. I have never been to one, but I guess they are less fun than the ones we used to go to without screens at all.
Update 1 August 2015
The most recent edition of the Schengen guidance contains this text (a screen cap is being used so that the information will persist if the link is changed)...
Item (b) in this list explicitly states that credit card statements are acceptable as evidence.
This makes so...
