My friend has just had this offer sent to her too - and she decided to go for it and make the booking.
However.............
When she tried to book for the dates she wanted, the Hotel didnt have a room available, so she has booked to actually stay at the Marriott Village in one of the Villas. The only difference is that it didnt include three days of Passes, just one.
Second however...........
She is going towards the end of July, and they have upgraded her day passes to Three Day passes for all four of them (2 adults - 2 young children) and the total cost is a £390.00
Now, all she has to do is sort out getting there and she is well away!
They are hoping to also book or take a tent to do some camping either side of their visit to DLP.
This will be their first visit to DLP, although not to France, and I have given her a link to this board as I know she will get lots of info from everyone.
