No I did not purchase travel insurance.
Well everybody has a diff perspective on what is acceptable. For me, this was the first cruise for the whole family and we had spent a lot of money for the whole vacation and planning the trip for months. It definitely was a huge disappointment e.g. my wife complaining about no clothes or cosmetics, no night dress to wear for anybody, no swimming costumes for the kids, having to laundry everyday, no shorts or tshirts to relax in, spending hours trying to find reasonable priced clothing (everything was in the $50 - $100 ranges, shaving with disposable razors, spending hours on the phone with AA and Cruise line people instead of enjoying the trip etc. I could go on and on...
Having spent over $5K, this was no way to have a relaxing and fun vacation. Who knows when we will take the next cruise.
