London to Paris Aparthotel Adagio Access Nogent sur Disneyland Paris 13/08 - 20/08 2 adults breakfast included

Very decent price for a week in Paris, but keep in mind this accommodation is not close to Disneyland Paris, and it's not close to the Orly airport either, which is where you'll arrive with Vueling. The closest rail station is on Line E of the railway. So getting to Disneyland will take about an hour on the train. (Nogent - Le Perreux station to Val de Fontenay then change for Line A to Marne-le-Vallee Chessy for Disneyland.)

The accommodation does have a 74% rating on booking..com so it's a decent price if you can get to Gatwick cheaply. And it's just after the Olympics so Paris should be a little quieter after all the sports fans disappear. (edited)

Breakfast seems not included
