Hi. Which Mayo Campus will you be visiting? We have members who’ve visited each clinic and can help you with information about the clinic, lodging, getting around the city, dining, etc.

It’s pretty customary for blood tests to be drawn first thing in the morning. Make sure you arrive 30 minutes early for your labs as it’s super busy there. The labs are run immediately and results will be available to your doctor by the time you’re up at your appointment!

By now you have a Mayo Patient number. If you haven’t done so already, go online to set up your patient portal in online services. The portal is main communication with Mayo.
https://onlineservices.mayoclinic.org/content/staticpatient/showpage/patientonline
From this portal you’ll see all your appointments, your health records, letters and notes from your team, medications, etc. Once you see the doctor for your consultation, things can happen rapidly. I don’t know your situation so I’m not sure if you’ll have more tests that day or not.
It’s difficult for the staff at Mayo to schedule more appointments before you see your specialist as they don’t know what tests you might need. That will be determined after your bloodwork and consultation. You can also use this portal to contact the doctor’s staff where you’ll be seen. You can send a note or call to ask about what the timeframe for staying near the clinic might be.

If you’re from out of town and uncertain how long you’ll need at the clinic, you might consider staying another 2 or 3 days. Hotels are pretty good at working with patients with cancellations.

As far as I know Mayo doesn’t have appointments on weekends or evenings.
Did you set up your portal yet?
