ST. PETERSBURG, Fla., Dec. 1, 2016 /PRNewswire/ -- As wave season begins, many travelers are taking advantage of cruise sales to book their next vacation. Squaremouth, a leading travel insurance comparison site, shares three questions travelers should ask themselves before buying travel insurance for a cruise. Should I Buy My Cruise Line's Travel Insurance? Travelers with specific concerns should compare the insurance offered through their cruise line to that of a third-party to ensure they are getting the coverage they need for the lowest price. Third-party travel insurance is often more comprehensive compared to what's offered through the cruise line, which may limit benefit amounts or remove coverage altogether. Travelers who book insurance outside of their cruise line are also able to insure all of their expenses, including any additional flights or hotel stays. While cruise line insurance may cover Trip Cancellation, it will often only cover flights and hotel accommodations booked through the cruise provider. Likewise, their Cancel for Any Reason coverage provides a cruise credit instead of the cash payout offered by third-party insurance. How Much Medical and Evacuation Coverage is Enough? For travelers going on extended or remote cruises, medical bills can add up quickly, especially if an evacuation is required. Squaremouth claims expert Brandi Morse recommends cruisers purchase at least $100,000 in Emergency Medical coverage and $250,000 in Medical Evacuation coverage, adding that "shipboard clinics can be quite expensive compared to your doctor back home."
