You need to look up the meaning of "glitch" then. Understand the words you use.
The chances of another group of 18 people wanting to fly from Leeds/Bradford on those exact dates, to the same destination and willing to be crammed into 3 apartments is probably next to nothing !
Please can you with your wonderful wisdom explain this comment. The price is far more expensive with any other number of guests. 18 is very cheap.
Cold, you don't know the meaning of glitch.
Very good price really, but like you say 'narrow market' but really is perfect for a group of friends or a stag / hen party
