I bought the discounted sun pass mid-Dec and ended up having to buy a regular sun pass 2 weeks later.

I have now used 5 credits of the regular one and none of the discounted one since with the middle 3 days of the week (or was it 4?) and the availability issue, I was not able to use any of the discounted credits so far. I wish I had just bought the regular one but that was one of the first pass I purchased and I was a little unsure if I would go to LAS or FL 3x. But with several conferences and meetings there, it has been very useful.
