I wanted to find a fun active thing to do by myself for a day, since the people I traveled with would rather spend their day shopping and eat ing/drinking. Receptionist in the hotel Casa Iguana recommended the Shamballa cruise, which represents itself as a cruise providing continental breakfast, lunch, snorkeling Los Arcos rocks, trip to Las Animas beach, and hike/horsebck to Quimixto waterfall, with an open bar and party atmosphere. The continental breakfast was simply fruit and juice, no bread, so I was starving right off. The open bar was nice, and I made friends quickly with a group of Mexicans who amongst them had a gal my age, who was a bilingual US citizen of Mexican descent. So it was very fun and friendly and social cruise. I was one of only 4 other non spanish speakers on the boat. At first it was OK because they translated for me, but as the trip wore on, they stopped doing such, so I went around kind of wondering, or asking my bi-lingual friend what they were saying. I was disappointed by the snorkeling. Although the rocks and water are gorgeous, the boat didnt provide fins, and they let us snorkel for only 15-20 minutes at best. I was expecting at least 40 minutes. The biggest problem came at the trip to the beach, Los Animas. Nobody informed me in English that we were going to be having lunch off the boat, on the beach. So when my friend told me this was what was happening, I got my lunch voucher, camera and sunblock in my hand and got on the little panga. I must have lost the lunch voucher in the ocean because when I got to the restaurant, I didnt have it. I told the tour leader guy suck and he said there was nothing they could do I would simply have to buy my meal. Which was ridiculous, I had paid for it and the y had prepared the meals in advance. So the one leftover fish lunch that was supposed to be mine didnt get served to me because I had lost my ticket. Not one of the Shamballa staff would accomodate me, so my mexican friend actually gave me her lunch and bought herself another lunch, even though I could afford it and offered to do pay. So gracious!! (Thanks again, Claudia!!) That tratment by Shamballa really pissed me off, althought I kept my cool. There was an opportunity to swim after lunch, and after returning to the boat, we went on to Quimixto, where we hiked an quite enjoyable strenuous hike (you could ride a hrse if you wanted) to the waterfall, which has a cold clean pool to swim in, and a small restaurant serving drinks. That was totally enjoyable. On the way back to PV, they played music and had games and contests, all of which were very enjoyable. Once in port, the propina (tip) jar went around, but all I had was 200 pesos. I told the man I needed cambio (change) so after every single person got off the boat, my friend (and savior) Claudia "reminded" the man he had not yet given me the change. I told him I wanted 180 back, so he would get a 20 tip ($2.00 US, which I felt fair) So he handed me 180, and then gave me an expression and words about never having given him a tip! Like, Duh I was stupid? I gave him 200 and had 180 in my hand! So I said to him, "I already gave you 20 pesos tip, senor." Then my friend Claudia told him in Spanish he should be ashamed of his trying to cheat me just because I didnt speak Spanish well I wasnt a fool. Then we got off the boat and all went our separate ways. Warning to anyone doing this trip, the people running Shamballa are fun and entertaining, but in the end they wouldnt even try to do anything to recompense or aid me for my lost lunch voucher, and then they tried to double-dip my tip. Fun tour, great friends, but beware and be savvy. Dont let these jerks rip you off in the name of a good time.
