Princess' insurance is good if you are looking to be able to cancel for "whatever" reason. Regular insurance gives you 75% credit and Gold gives you 90% credit. This is good if you are thinking you may have a work emergency which may interfere with your travel. Since you usually have to pay extra for this option with other insurances, Princess' price doesn't seem as great. If you don't need or want this option, ask your TA about the different types of insurance that are offered.
