Call later in the day if you can( like if you are tweeking the adrs0..Alas, there is light at the end of the tunnel, eventually you will be able to do adrs on the internet( which initially will probably have a whole host of its own issues)
I finalize my ADRs for the 4 days I will be there. The only one I did not get was Crystal palace and there is a story behind this one, the first time I went to DW I was 17, 1975 now at 51 I figured I should go there. when I first went to DW that was the only park, amazing how they grow over all these years
