Flight Advice Please!

[amacspad]

Hi, thought we wud book a week at the world on 29th June after my daughters exams, paid deposit with Disney to stay at pop, flights with monarch were £459 so thought I would hang in in the hope they would drop, this morning they have gone up to £479! Do I wait or just book, I was hoping for this week to be as cheap as poss, last year they dropped 3 times!

Please can someone advise,
TIA, Debs xxx
