from Airport to DL how long?

[Leofoenget]

OK I booked my flights (southwest $49 special yay) It gets in 6pm on a wednesday afternoon. SO how long is it gonna take to make my way from the Orange County airport to my hotel BWPPI that time of day? I have made the drive mid morning and it didnt take more than about 15 mins. Is that time of day major commute time? gee I hope it wont take me forever to make my way to the hotel. Mapquest says I have to go on the 405 for about 1/2 mile I have heard horror stories about the imfamous 405!!

anyone?

thanks
