Excursion/Cabana price changes?

[WDisneyWLove]

Is anyone aware of any pending excursion or cabana price changes? I booked cabana a few weeks ago and logged on today to check what the price was and noticed it says "price pending". I'm pretty sure it was $590.18. Can I be charged more after booking at the original price?

I noticed the same for some excursions I booked. When I booked there was a number and now price pending
