We are from Sarasota and we usually leave about 8 in the morning and always get there by 11:30 or 12:00 depending on the traffic. We also always stop for gas and breakfast on the way. We travel I-75 North to I-4 East. We take the (I think it is the 417 Exit--anyway it is the Celebration exit to the airport in Orlando). We find this saves the backups on I-4 and is much quicker (although it is a toll road). Then we get on 528 which is the Beachline Expressway(this used to be called the BeeLine Expressway) and follow the signs to Port Canaveral. If you leave by 6:30 or 7:00 in the morning you should be okay. Remember your room will not be ready until 1:30 so getting there really early is not really all that important.
