I would have to agree that the pricing is getting way too steep.
I know it's only $100 a day, and can be considered cheap compared with an overseas holiday, or touring in a car and staying at a motel, etc
But now that I'm semi-retired and want to do a lot of cycle touring, it's over the top to spend $1300 each time.
I've joined a local cycling group, who organise tours from different places. We go to a Caravan Park and camp, then go out on different rides each day. It doesn't have the glamour of a tour like the Great Escapade, and you don't go from A to B a long way away. And you have to cook yourself each nite, pack up and move on if someone has a van.
But it is a lot cheaper way of doing it. I hear Bicycle SA puts on a less-costly tour, where you stay at caravan parks etc. I might do one of theirs next, but this is the last BV tour that I will do; too expensive
