I think it's purely down to what saves the most money in terms of staffing, not ride cost, but they will have looked to spread out these late openings across the park so that the impact of it seems small. Whereas if all the rides were in one area it would be much more noticeable.
I would have thought opening Rita later would save considerable amounts of money in terms of power but obviously not.
I dont know the exact number of staff for each attraction or how much they get paid, but if you reduce 10 rides by an hour and each has 5 staff getting paid £6.00 an hour then that's £300 a day saved or £9,000 a month.
I'm sure it will actually be a lot more than that. Someone more knowledgeable than me on these matters should do a precise calculation
sounds about right but that gets me thinking
you're probably looking at an average of 6 or 7 staff per ride if you include their break cover. if we just go with the higher value, just for arguments sake, then your looking at £420 a day and £12,600 a month. or even £61,740 for the remainder of the season.
plus the electricity saved, i don't know how much it costs to run a ride for 1 hour, but i think £250 per ride should cover. it so that's another £2500 a day
doing some more calculations, based on a 3000 gate figure (which apparently is the average this year) with that full figure split evenly to 4 to a car (unlikely i know), and all cars in paid parking, they will take £4500 a day, just in parking fees. now I can assume possibly 10% loss in hotel guests and another 10% for premium pass holders which brings it down to £3600 parking income per day.
now lets work out gate takings, this is assuming that 50% of guests have BOGOF vouchers or pre-booked discounts, the same 10% premium annual pass holders, plus 10% standard, and then there's people with hotel discounts, and child tickets are cheaper too. so i think a nice low figure of 30% of that gate figure paying full price ought to cover everyone (feel free to dispute this if you want), and i make it £37,800 in gate takings per day.
now lets assume that every group of four spends £130, collectively, on park (my group did so i think that's fair). this covers food, drink, photos, souvenirs, and the odd fast track (being as i personally spent quite a bit on souvenirs). and i make that £97,500 in general park spend, which is probably an understatement
and our grand total for the days takings is £138,900. and that is a quiet day and probably an understatement. as there are many other things i didn't factor in, such as pay to use attractions, games stalls and arcade takings, being as i never spend any money on those anyway. if i round up to include those however to say £150,000 a day. which equals an average of £50 per person per day
so merlin strapped for cash? un-bloody-likely
