Torsie, you are allowed to come out of the Princess Pavilion queue for 20 minutes at a time (for a loo break). They give you a numbered ticket on entry now and if you want to go out, they take your tag, write your number down and the time you left, then you pick it up again on your return.
Just a thought in case you decided to go for it.
This is what we did last week and boy were we grateful to get some air!!!
