I"m looking at cruises at the end of March; however, if I use a party of 3 I get full availiabity. If I do 4 less cruises are available; however, if I split up into 2 state rooms those same cruises are available so it's not a total capacity issue. However, when I go to book 3 and this room shows available with this description I should be able to book for 4 but once I change it goes away. Why is this happening? Has anyone seen this?
