I say do it!
My daughter and myself are Platinum, her on her 10th cruise, and it was my 24th. We have three friends that cruised with us that are not Platinum. As soon as I heard about the faster to the fun pass, I called them and told them to purchase it. Personally, while I did not like the fact that others could just buy into perks that we have earned, over many cruises with Carnival, I just thought ... well if others are doing it, why not them??
Our plane was scheduled to arrive at Miami at 10:40. We arrived early... 10:20. We shared a cab/van for the ride to the port, with a quick 10 minute stop to purchase cranberry juice to mix with the vodka that we ordered from room service... that worked out very nice by the way.
After arriving to the port, our luggage and their luggage was put in a different area that those that are not Platinum, Diamond or faster to the fun. We went together through the security line. Our friends asked us to wait for them after getting checked in, because they wanted our embarkation pic taken together. We went to the front of the line where they were taking faster to the fun and vip guests, including Platinum.
The security line for us was very fast, then they sent our friends to the faster to the fun line, and us to the Platinum vip lounge. Our friends were boarding immediately, us... not so much. Our friends kept calling us to find out where we were... well... we were sitting the the lounge waiting for them to call our names. Finally, when we get done getting checked in, and standing in another short line, for our sail and sign money to be applied, we headed to the line for boarding. Got to the top of the ramp, sorry we were told... you have to go to the back of the line ( a very long line by the way ). I showed him my card and told him we were supposed to get priority embarkation,... he said go to the back of the line... so we did.... Our friends had already boarded and eaten their lunch at the buffet by the time we got onboard... and were waiting for us... It actually took us almost 55 minutes from the time we arrived at the ship to the time we boarded. While it doesnt seem like much, we were told that the security cameras show us boarding 28 minutes after our friends... yes, they have good security when they can actually go in and look at the time you boarded by the camera.
Anyway, faster to the fun worked great for them! Onboard within 27 minutes after arriving.... I was happy for them... but we would have been onboard faster if we had paid for that instead of with our Platinum card. We were told at the guest service desk that the idea of Platinum boarding is so you can sit and not wait in the line. I always thought it was to get you on faster. I would have preferred that they put us all through the same line if this is how it is. Instead, we were sitting in a room with about 20 others, with empty lemonade pitchers. Oh well... to those thinking of booking faster to the fun, do it! It worked out great for our friends...
