If you have traveled several times on a cruise ship you will have realized that sometimes, you may be lucky, that when you arrive Upon boarding, the shipping company upgrades your cabin category and accommodates you in one of a higher level than the one you booked. For example, we may have paid for an internal stateroom and find ourselves traveling in one with a balcony.
If this does not happen, and the shipping company does not offer you this cabin change, we are going to give you some guidelines so that (perhaps) this situation changes. For example, there is the rule of Update, that is, "a cruise ship with all the cabins full is better than one with a few empty cabins."
This idea means that the company does everything possible so that when the departure date arrives, all the cabins are sold, but passengers who had reserved a category of cabin in high demand, and the others are not occupied, then they are The defendants are released, and it is always done by leaving the easiest to sell free, because they have a lower price. So when we go out the shipping company analyzes the occupation progress of the different categories of cabins and "redistribute”, Offering travelers who occupy cabins of greater demand to change. All this that I have explained to you is a common practice, but not an obligation of the company.
Make book well in advance it will also help our name jump on the list to be relocated as it is one of the parameters that the shipping company is analyzed when choosing which customers will benefit.
Another issue they take into account is be a partner or friend in frequent flyer programs, or loyalty.
