I'm willing to be persuaded. I'm just naturally suspicious of dual navexs that involve landing somewhere agreeable. Its always at the students expense and sometimes has dubious training value but is a nice day out for the instructor.
That said I used to engineer it myself to take a couple of students off for the day and do some landaways in Faro and Granada for lunch. It can make a pleasant change for everyone and make the training more enjoyable for Bloggs.
Or it can be a lazy arsed freebie for some hour building clock watching scum of an instructor who probably eats babies or something.
Take your pick.
Cheers
