Well ....
The bullet has been well and truly bitten, chewed and spat out! Today the flights have been cancelled. Tonight the hotels will be cancelled and the planning for TDL will need to be put on hold. When we finally do it we will more than likely plan much further ahead and get the cheap rooms through the Hilton, and also make sure the currency is less of an issue.
Reason we decided to do this was because if we travel to somewhere like Japan, we want to see Japan and all it has to offer. I worked out we could cut the trip to 7 days and fit into the original budget, but we would want to spend more time there than 7 days - and the decision to cut down on seeing Tokyo and surrounds or reducing days at the resort was way too hard to make.
We'll have to make other plans now ....
