When my wife (Alison) & I (Lauri) were there in 2007, there was also an excursion booking table set up in the lobby. The company was Vallarta Adventures. We went deep sea fishing (caught Blue Marlin, tuna, dorado, wahoo), snorkelling, sunset cruise...I think we were on the water 4 of our 7 days so I'm forgetting one. We had the Best time!
When we did the Olivia cruise from San Diego a couple of years later, we docked in PV & I could see one of the Vallarta Adventures boats docked next to our ship. I went to it & the same Captain was at the helm as had been on most of our excursions in 2007. I went to him, said Hello, reminded him where/when we'd met & he remembered me! I'm hoping that Vallarta Adventures is still doing a great job with Olivia & still Olivia's preferred excursion supplier. You know I'll be looking for that captain too! One of the things that was soooo great about him is that he was very willing to talk about his life, his family, his children (we had brought kids' stuff~yoyos, hair ties, pencils with Canadian flags on them, matchbox toys etc). We felt like we got to see a bit of the more human side of PV & not just the Tourista side.
If you're checking these threads out trying to decide if you want to come on the trip, don't wait any longer! BOOK IT!!!
