You did not mention what Mayo campus your going to, but if in Rochester on Thursday, there are food and craft vendors set up on downtown streets few blocks from Mayo buildings (weather permitting). Great place for lunch, listen to some music or kill few hours between appointment.

Also, if dad is in wheelchair and needs assistance in getting him from one appointment to next, ask for a escort / transporter. They can help push wheelchair where you need to go.

Bring light sweater if tend to get cold, some rooms are colder then others.

Good luck with appointments
