Disney site, flights included?

[madmumof2]

I'm having a look around and doubt these are cheaper than the £3370 I've found so far but I still want to look, but the site doesn't seem to work for flights included holidays.

I get right to then end where it asks you to choose which holiday/flight and it says all are unavailable, doesn't matter what dates or hotels I put in.

Is this a glitch? I remember this happening last time I went in 2009, has it been like this since then?? lol
