advice on eurostar paris day trip with signtseeing cruise

Economical

Hello, i am doing the above day trip next week with 2 kids but we've never been to paris. So would be grateful for any advice on what to do there. We arrive at Paris Nord station at around 10 am. from there where do we go, where can we have breakfast? how do we get to Eiffel Tower and reasonable price places to eat, and any other places that we can go to within the day as we depart at 8pm. something entertaining for the kids would be good they are 12 & 5. Any advice/recommendation would be really appreciated. Thank you

Would really need to get a paris metro map try on line , get metro to concorde station , here you will find eiffel tower plus river cruise terminals , as you only have a day just stay around here then get back to gare du nord. hope this is helpful.

Thanks for the reply Thamespirate. Now I know which station to get off. I will probably stay around that area too.

It may be too late if you are off next week since you receive the vouchers by post, but you can get some tickets with clubcard vouchers -

Cruise. Lasts 1 hour.
Montparnasse Tower. Very good, but I think the outside viewing area is closed at the moment.
Aquarium. Though I would think that would be too time consuming on a day trip.
