The Mighty Amazon River has long been on our bucket list, & the newly refurbished Sirena's 34-day sailing from Miami to Buenos Aires sounded like the way to go!! The first week at sea was uneventful & unexciting, as we bypassed devastated Puerto Rico, & visited St Kitts, Antigua, & Barbados! We enjoyed the day we spent exploring the ruins of Devil's Island, the former penal colony off the coast of French Guyana. Unfortunately, we were totally taken by surprise as it was announced that almost all purchases aboard ship for the next 3.5 weeks (as we sailed thru Brazilian waters) would be subject to an extra 25% tax. (We solved this problem quite simply, by halting all unnecessary shipboard spending!!) Almost everything was included in our ticket price: air, gratuities, 7 shore excursions per person, internet package. There were no art auctions & no pushy shipboard photogs to contend with. We were not nickled and dimed over soft drinks, specialty coffee, & bottled water. Since the Sirena drew only 20 feet of water, We were able to travel 900 miles upriver to Manaus in the heart of the triple canopy Amazon rainforest. While the destination speakers for the Amazon region were well chosen, the Oceania home office staff of millennials let us down when it came to providing suitable movies that might have dovetailed with our journey!! As we entered the River Platte, it would have presented a great opportunity to view "The Battle of the River Platte". It would have also been timely to have watched "Evita" again, as we neared Argentina. Instead we were subjected to current, inane films, such as one depicting Breaking Bad actor Cranston hiding out in his garage for several months!!! We manged to dine in Sirena's Specialty restaurants on numerous occasions - especially in their magnificent Red Ginger Asian Fusion spot. Afternoons the main dining room was converted into Jacques - a specialty French Bistro - with mixed results. The Waves grill by the pool closed way too early @4PM.
