We were there on the last day of F&W, a Sunday, several yrs. ago, and it was a madhouse. It was hard to walk around WS, and this was in the afternoon. We had kids with us, so it made it harder to navigate around all the people wandering around enjoying their drinks. I would imagine unfortunately for you that the whole weekend will be very busy, since it is the last chance for people to go, and lots of locals come on the weekends anyway. Since you are staying right there, you can always go for a while, and if its crowded, you can always go back to your resort and take a break and go back in later, or hop to another park.
