I was looking at that last night. It looks like I couldn't get any info regarding their Disney cruise partnership, prices, or order test kits until I created an account with them, which you can't do until 15 days before your cruise. I want this all settled before that.DCLs testing partner Inspire Diagnostics also offers a proctored (virtually monitored) self-test. Price is the same ($45 each) as if you use one of their in-person locations.
I think the emed.com pricing and arrangement work best for us.
