Most brides schedule the hair and makeup early in the morning.
Often when brides arrive late it is because the hair and makeup took longer than planned. You might want to schedule an extra appointment with them prior to the wedding day to do a test run so that you are sure you will like the results. Also do a test run with your bridal attire to make sure everything fits the way you want so you don't have to fix anything last minute on the day of the wedding. If you are having photos done your photographer should provide you with a schedule for the planned portraits you may want. The DJ usually works with you to write up a schedule of all the events also.
