Downtown Disney is currently open. There is outside dining with limited capacity. If your friend will be visiting before March 15th, part of DCA is open (BVS and some parts extending toward Monsters Inc. and toward Grizzly Peak and toward Soarin') as an extension of DTD. March 14th will be the last day DCA will be open for free to guests of DTD before it reopens for the ticketed Touch of Disney event. If your friend is interested in visiting DTD next week, have her look at the DL website or at the DL app for information.
Your friend's hotel (e.g. front desk staff or concierge) should be able to help with updated information on what has reopened and what the current safety guidelines are at the time of her trip. Tell your friend to check online ahead of time before visiting anywhere to be aware all safety requirements, e.g. masks, reservations, time limits, etc.
