Thank you all so much for your comments and views, they have helped enormously.
We were thinking of trying to budget for this August for two weeks as we have AP's for WDW/BG/SW. It would be on a shoestring budget with no bells and whistles! The very basic of everything including eateries and car hire.
The main reason being I can't get the time off from work for our usual length of stay next Chrustmas Another factor will be if DH can get the August 2 weeks off from work.....he has the holidays but will only get them approved if no one else has booked the same dates.
Any money saving tips are very welcome
