We are going that same week and I have had our tickets for a bit. I know that the tickets for the flight I want NEVER go on sale because that flight is ALWAYS oversold and they are ALWAYS asking for volunteers to leave later (sorry, you can't compensate me enough for lost park time
).
I was really worried because I kept hearing about the cost going up and up and up, so I took the plunge last month.
you find something you can deal with!
