We are considering several ships for an upcoming fall cruise, and have various coupons for discounts and some for upgrades. We also have 2 $30 off Carnival coupons from a class action suit that took place a while back. I phoned Princess's reservation dept. to ask if these could be used on a Princess ship, since Carnival now owns Princess. The agent I spoke to said yes. However, today a T/A said they tell you that, but then they don't allow the use and want the coupons tied to the original line. Also, I asked about an upgrade coupon we rec'd. from Princess. The T/A also indicated that Princess wouldn't allow those to be used on the lower priced promotional fares which are lower than their early booking fares. One last thing, the agent indicated that the Dawn Princess' passengers tend to be an older crowd. I knew this about HAL, but Princess? We have sailed RCCL a lot and I'd always sort of figured Princess to be similar in many ways. Can anyone shed any light on any of this? Thanks.
