Taking a Galapagos cruise is considered the best way to explorer the Galapagos as it gives you the opportunity to reach the remotest islands as you sail at night from site to site, which means more time to enjoy the location and day’s activities.
However, if you are susceptible to sea sickness the feasible alternative is taking a nice land-based tour with hotel accommodation on the populated Islands of Santa Cruz, San Cristobal and/or Isabela; from here you can enjoy interesting day-tours to the nearby sites or Islands; you will also have the possibility to enjoy snorkeling and other activities while taking day-tours.
There are no established tipping guidelines for all cruises, you should decide the amount to tip your guide and crew based on your level of satisfaction with the services provided on board and while on excursions.
On Luxury and First class cruises it is recommended to tip $15-$20 p.p. for the guide per day and the same amount per day for the whole crew. On Midrange and Economy class cruises it is recommended to tip $10-$13 p.p. for the guide per day and the same amount per day for the whole crew.
