I think it's a really bad idea but smacks of a money grabbing exercise and can't see the gain to the actual sport. Four days are exhausting if you want to go for all of it, and that's from someone who doesn't drink while they are there, and doesn't have to drive usually for all 4 days to get there and back! Aside from that it's not inexpensive now and I have somewhere free to stay. I think the card at the moment on Gold Cup day is the 'worst' but if you want to be there for the GC, then one tends to put up with the rest of the day because of it. I have done all 4 days a few times but only because there's one race a day I really want to see. This year because of work and money, I only went for 2, the Thursday and the Friday, because I wanted to see Frodon and Bryony and was hedging my bets when booking tickets, but I would have loved to go on Bumper day, but had to sacrifice that for the two days. I think there would be a limit to how many could afford the 5, particularly those who have to travel and pay for local accommodation.
