Yes, nothing is ever sent out in the post - the confirmation that you need to show at the hotel is sent by email. Your park tickets you also collect at the hotel when you check in.
Arrrggghhh!!!! MIL is coming round this afternoon so I went to double-check the prices for SL & HNY for our dates and the 30% deal is gone already!!
If anyone's thinking about it I'd say book now before the deals go! I am off to play around with dates - I'm sure I can still get the deal somehow - fingers crossed!
