Each cruise line is different. Celebrity, Costa, Cunard, Disney, Holland, MSC, NCL, Princess, and RCL, Carnival all have high chairs available.
Norwegian, Celebrity, Holland, Princess, Disney and Cunard have cribs or pack-n-plays available that we can reserve ahead of time.
Pack and plays can be requested from Carnival, Costa, Royal Caribbean, and MSC but they have a limited number. We recommend that you bring your own just in case since they allow this on MSC.
