Just rang on the discounted telephone number as recommended on here - many thanks for that. Got the times we wanted as well so I am now a bit giddy!
When booking Chef Mickey for 23 rd September she did say that it was only open until 5pm - so not sure if this is correct. I booked for 12 o clock and included my birthday cake yipee. Also got Plaza Gardens for 12.30 on the Wednesday and Hunters Grill for 6 pm the day of my birthday. We had wanted to do Agrabah on the Friday but it of course is closed as we know.
All the advice on this forum made that very simple thanks to you all.
