I'm coming in May 6th to May 15th for a knee replacement from John Hopkins and was wondering how early will I be able to get in my room??

Call them ahead of time and they should be able to accommodate you depending upon how booked up they are. If you're a member, you can checkin online, and request your arrival time

I was able to get my room at 2. If there are rooms available they dont mind an early checkin

Call and speak to the front desk. Being that guests arrive at any hour, there is no 'time limit'. Call and book the room. Being a Surgeon, if your surgery is pending depending on where you live. Feel free to plan your trip around the day of admission so that you will be NPO after dinner and make your way to preop admitting same day. If from out of town. Book your flight to arrive as early as possible pre OP. If unable; pack light and figure out arrangements for post OP discharge. Good luck and God bless you.
