I will be there at the same time, and I'm not getting an EP. I don't think it will be worth it. Hope I'm not wrong.
But the crowd levels are listed as low, and if you check the corresponding wait times for the individual rides there are only a few with waits projected to be over 20 minutes, and those are mostly the ones that don't take the EP anyway.
When we went this past spring the crowd levels were much higher than what is being projected for the end of January. We had EP, and they were nice because we had a few family emergencies that messed our trip up. But honestly, with a little planning, rope drop, and no ER visits, we could have made do without the EP and still not waited very long. Could the kids have rode the coasters over and over about 20 times each? probably not. But they still could have gotten a few rides on each caoster in. We didn't have the EP our last day which was a Mardi Gras concert day, and we still only ended up waiting in one 25 minute line all day.
