Is Royal Caribbean strict on underage drinking?

Is Royal Caribbean strict on underage drinking? Ugh, it's SO frustrating! Seriously, if you're under 21 and you're cruising from, like, Florida or the Bahamas – forget about it. They're ridiculously strict. I remember my cousin, Sarah, she was 20 on her cruise from Miami – couldn’t even order a Shirley Temple without someone giving her the look. Talk about a buzzkill.

But then, get this – if you're sailing from, say, Barcelona? Eighteen's the magic number! Eighteen! It's totally insane, right? I mean, what's the difference? One rule for some, a completely different one for others… it just feels so unfair. Like, are they really that worried about some teenagers sneaking a sip of something? I don’t know, man. It makes me wonder if it's all about different legal systems or something. I've heard whispers it's to do with which country's laws they have to follow while the ship is in international waters... something about flags and international regulations, but honestly, it all sounds like a huge mess to me. I wish they'd just, you know, pick one age and stick with it. Makes for a way less stressful vacation planning experience, wouldn't you say?
