On December 10‚ Royal Caribbeans Serenade of the Seas set sail on the Ultimate World Cruisea 274-day global trek that visits 11 world wonders and over 60 countries. This incredible trip covers the Americas‚ Asia Pacific‚ Middle East‚ Mediterranean and Europe with a ticket price that ranges from $53‚999 to $117‚599 per passenger.Aboard the Serenade to the Seas is popular TikToker Marc Sebastian‚ who has been sharing his experience on the platform.In a recent video with over 4.3 million views‚ he revealed what hes learned over his first few weeks aboard the ship; the biggest was the one word youre not allowed to say: Titanic.Who knew that? I didnt‚ Sebastian said. I brought it up to an entire room of people having lunch that our ship is only 100 feet longer than the Titanic when I tell you that utensils dropped. Waiters gasped. Its dead silent.@marcsebastianfsomeone get whoopi on the line girl i have some goss for her #ultimateworldcruise #worldcruise #serenadeoftheseas #cruisetok #cruise #9monthcruise #titanicAfter the unexpected reaction‚ his cruise friend told him‚ Youre not allowed to talk about the Titanic. It makes sense. Who wants to be reminded of the tragedy that killed around 1‚500 people while sinking one of the most impressive engineering feats of the era? ";When I went on a cruise‚ my mom told me saying Titanic was equivalent to screaming bomb at an airport‚"; Mikayla wrote in the comments.Later in the video‚ Sebastian admits he was surprised to learn that cruise ships have godmothers and that the pools are filled with seawater.This article originally appeared on 1.25.24
