Sea World in January

[Neats]

I am looking for some help. We will be in Orlando for 2 weeks in January. Just wondering how busy Sea World will be on the Saturdays that they have kids concerts on. We want to take our daughter to Sea World for a day and do the Dolphin Up-Close and personal tour. Would like to do it on a day when they also have the concerts on and the park is open an extra hour. But if it's going to be crazy busy then I would rather do it during the week. Can anyone tell me what crowds might be like on Saturday's during the kids concert series. Thank you!
