Firstly, I'm in London too tommorow (but before you'll get there (doh!))
Secondly, you planning on telling her you love her on the London eye - ahhhhhh
Thirdly, it says on the London eye site
Can I take large bags or luggage on to the London Eye?
Large bags are not permitted on to the London Eye. For a better understanding of our safety and security policy click here. Please note that no suitcases, backpacks or heavy bags will be accepted onto the London Eye.
Fourthly, if you had bothered to ask I probably would have been able to arrange a room at Thomies where you could have put it, but did you bother to ask? Nooooooooooooooooo
Fifthly, you wuv her, ahhhhhhhh
Sixthly, the only place I can think where you could put the bag would be lockers at Waterloo - I've never seen any, but surely they must have some.
EDIT:
