bgt - the new center parcs in bedfordshire may be open by Xmas 2010. Not sure though, think that is their aim date though.
The £25 vouchers are supplied as 5 x £5 vouchers which can only be used on the dates of your stay. They can't be used for booking AquaSana Spa Sessions or Treatments - unfair I feel, as those are what I book most. They can be used in the shops (including AquaSana shop) and restaurants - so I used mine to buy food and a magazine.
Booking tip... as already mentioned by some others but so important that I'll repeat it
Look at accommodation which has more bedrooms than you need. Then drop one bedroom and compare the price (and keep dropping to your minimum number of bedrooms). You can sometimes find that you can get a better spec villa, with more bedrooms at a slightly lower price than you would pay for something more basic with the minimum number of bedrooms.
Strange but true... did an example of it yesterday... 2 Bed Comfort Plus at Elvedon vs a 3-Bed Woodland... the 3-Bed Woodland villa was cheaper.
Mad4myboys - Patrick (think that's the name of the usual horse they use at Longleat - think I go to Longleat too often) is used to the route... could do it without the 'driver' and is on the flattest (well, least hilly) part, around Pine area.
