They seem a bit...disorganised in their organisation, shall we say.
I rang the website number (a mobile) to enquire about the trip I'm interested in, only to find I was talking to someone obviously driving, we managed a very short broken-up conversation before he was cut-off.
But turns-out the trip I was interested in hasn't had enough interest and they're not running it.
Kinda looks like it's run as a sideline business, not a big glossy holiday/tour company.
Which I guess could still mean it's a good trip : what matters is that the organisation and the leaders on the trip itself are good, not that there's a big expensive back-office.
And that the group dynamics work and the weather doesn't ruin it, of course !
