Hi,
I would book it all seperatly, you get the airfares cheaper that way. Bridge travel do accommadation only, but I still think you would be better getting prices direct. You can either book a package or just the hotel and buy the passes seperatly. An annual pass will give you hotel discounts.
It might be quicker to go by Eurostar. We are going in August and it only takes 2.5 hours from Ashford with only a half hour checkin. You are then dropped off directly at the park. We used airmiles and cash to do ours.
One point you may not know is that the hours drastically reduce in Sept. The park opens later and shuts early. Checkout the
disneyland paris web site
www.disneylandparis.co.uk for info on opening and shutting times.
Also if you want to stay on site, I would not stay in the Santa Fe and Cheyenne. The Cheyenne was better, but no swimming pool etc. The Santa Fe looked horrible and I would not ever want to stay there.
We have stayed in the New York and it was really nice, a bit formal. We have chosen the Sequoia lodge this time mainly due to expense. The Newport Bay looks lovely and I would love to stay in the Disneyland hotel.
I did run a price for 1/4 sept in the disneyland paris web site for two adults it was £658 that includes breakfast and passes. If you book with out a package you would have to buy the passes. Also there is the airfare on top of that. The airfare prices vary dramatically and it really depends upon which airline/airport you are using. The Eurostar would be about £95 return from London or get the Eurostar to Paris and a local train to Disney. This can work out cheaper. We have changed at Lill before an that was a lot cheaper.

They only publish prices 3 months in advance for Paris routs etc, but the Disneyland Paris train prices are out now.
