If time and money are major limiting factors for your Galapagos trip, then booking a 4-day cruise may be your best option.
Why choose a 4-day cruise?
The 4-day cruises are the bare bones option that still give you the ability to see the Galapagos. While almost half of the trip (Day 1 & Day 4) will be dedicated to traveling to and from the boat and not the actual activities, you will still be able to witness the beauty of the Galapagos Islands first-hand, which is a privilege less than four million people have experienced in this century.
For those looking to combine land-tours with a cruise, the 4-day cruise is a smart and affordable opportunity. Many travelers feel that five, eight, or fifteen days at sea is simply too much. If you want to experience more of the lively bar/ restaurant scene in addition to your cruise, then a 4-day cruise is a cool way to combine your time in town with your time aboard.
If you are concerned about getting seasick, then this is your best choice. Although larger ships or catamarans offer surprising stability, many people still feel that more than three nights on a boat can be too much.
