I just returned from a 7-day Mexican Riviera cruise on Royal Caribbean's Mariner of the Seas.  This ship is absolutely lovely.  I enjoyed every minute of my time on board.  The ports we visited were Mazatlan, Puerto Vallarta, and Cabo San Lucas.  We were supposed to stop in Cabo first but, thanks to Tropical Storm Patricia, we went to Mazatlan first.  The beaches in Mazatlan are beautiful to say the least but the drive through the city was, well um, not so much.  Let's just say I've been to cleaner, more inviting places.  Next was Puerto Vallarta.  It was nice there but nothing much to write home about if you get my meaning.  I was able to swim with dolphins there which was a great experience!  Finally, our last stop was Cabo.  Ah, Cabo!  We pulled into the marina at about 7:00 a.m. and I couldn't help but think how "sparkly" everything looked.  That's a strange word to use in describing a place I know but it's what came to mind.  I took a boat tour of Land's End and Los Arcos and it was beautiful to say the least.  I'd always seen pictures of it on television and in travel brochures and magazines but to see it up close left me speechless.  It's much more beautiful in person.  I'm so glad I went.  The whole cruise experience was a lot more than I expected.  I was pleasantly surprised by everything from the service of the crew on board to all the different activities there were to do on and off the ship.  If I had to do it all over again, I would.  In a heartbeat!
