Hi, I think it was mainly food prices (as that is where a lot of our money goes), we were on the gulf coast the first week and a lot of the entrees were $30+ in the local restaurants. Our first shop at Publix was $150 for breakfast goods, fruit (apples were £1 each) and washing powder etc.
When we went to Millers in Kissimmee which we considered a reasonable priced place, it cost about £80 for 2 starters, 3 main meals and 3 soft drinks. I think we were just feeling the pinch! Other people might think this is reasonable?
Other meals at WDW were obvious a lot more expensive.
