Saw this on MSE and am curious why it asn't been posted on here yet. A day trip to Disneyland Paris for 2 adults and 2 children, during half term including ferry and passes for £80 (£70 out of half term). It would mean a long day as it's a 3.5 hr journey from Calais to Paris but for that price I think it's worth it. Or you can have a one night accomodation included for £219 total (£199 in term time).
Book before Mon 21 Dec '09 for trips between Tues 5 Jan Weds 31 Mar 2010 inclusive. Dates excluded are:
Fri 12, Sat 13, Sat 20 and Sun 21 Feb
Fri 26 and Sat 27 Mar
Car parking at Disneyland Paris isn't included (around 10 per day), and there's a maximum car occupancy of nine people.
Disney has confirmed that you can also bring your own food and drinks into the park with you (excludes alcohol), so you can save cash by stocking up on snacks before you go.
Hope I've included everything lol
