Bit late to this but I was going to suggest that a transfer in Lille is far, far easier than trying to get across Paris. We didn't even have to change platform in Lille going out and the 'check-in' for the return leg is easy. Lugging a 4yr old and luggage across Paris wouldn't be my idea of fun!
Yep, direct, we are going in May half-term, I booked the hotel a few months ago but just booked the train now as I couldn't afford to book it all at the same time! Am quite excited now <even though it's ages away>.
If you go via Paris you will have to take RER B from Gare du Nord to Etoille change onto RER C and out to Marne Le Vallee this will add about one hour on to the journey with 2 kids and luggage. I would pay the direct price for the huge reduction in hassle and I regularly travel on the RER with DD and luggage.
I will be travelling with the DCs (aged 6 and 4) to DLP next year and I can't decide whether to pay the extortionate price for direct Eurostar tickets or to go via Paris/Lille? Is it worth it to take the train direct straight from St Pancras? Anyone done it and do you mind me asking how much you paid please? TIA
