That cant be right, if its 5/2 5/3 and your doing routes out of there that are 3-4 hour sectors you will go out of hours very quickly, or have tons on standbys.
Tenerife does sound appealing, and I mean to live there and not commute, could go home the odd time on the 5/3 by swapping a day so making it 5/4 but really just base there full time.
