Hello Muffin,
Which test are you using? The green box from the BC pharmacy? And which cruiseline are you using for? In the past, I used Switch Health for family travel. It is much cheaper to use healthcenter.ca for more than 1 person. Want to know if healthcenter.ca applies to upcoming Princess and Carnival cruises. On Switch Health, we don't stay online for the waiting period, they will email you the result which can be downloaded onto cruiseline website and verifly (if using HAL or Carnival). I used a pot (something heavy) to stand the cell phone to do this test.
Good luck. It will all work out.
PS, I am from Duncan, Vancouver Island
