My brother and his wife are still cruising. We booked a suite to have more room for the 3 of us. We then split the cost. So, if cost is 1,000 for passenger 1&2 and 3rd is 10.00 we split 2,010. I suspect I will eat the amount I paid extra but can't be helped. My insurance does cover for him being ill and I am his primary caregiver. I do have a travel agent and will contact her first. Just wanted to know what I may incounter. This would have been my first cruise on Carnival. Thank you all I'm grateful for the suggestions!
