I went on the same boat last October and booked again because every single aspect of the trip exceeded my expectations. The itinerary and staff ratio led me to book the first time, but the food, accommodations, and crew made it an easy choice for trip #2. The islands are wildly different depending on the season, I definitely recommend going more than once!
The guides are excellent and the small groups lend to not only seeing the animals up close but also amazing pictures. If you're into focusing on the scenery other guests are always glad to share photos (airdrop saved me this trip as I left my DLSR at home).
I've done both trips solo but would also return for a 3rd (or more!) trip with a friend or my boyfriend. I'm sure a +1 would be great but as for solo trips, booking with Quasar is by far my favorite. The other guests are good fun and every detail is handled making this the most refreshing week ever. I love that there is no guest phone/wifi service on the boat, I hope that never changes.
Food is excellent. I'm vegetarian and was very impressed with their attention to detail and always having separate plates for those of us with dietary requirements/preferences. I requested almond milk and on the first breakfast I was promptly brought a glass before I could even pour my coffee.
Outside of the boat, Quasar's level of service is remarkable. I (half-joking) emailed Diane for a local orthodontist recommendation since I melted my retainer on day one of my week prior to the cruise, when they didn't catch me at the hotel - they called my guide en route to our excursion with an appointment scheduled that day. I was impressed but not surprised given their excellence with every other detail of my previous trip.
Speaking of recs, Diane's suggestion to stay at Hacienda Jimenita the week before my cruise was also wonderful and I would definitely stay there again! I didn't even have to think of my flight, Quasar organized everything with the hotel for my transfer and pickup time.
I cannot imagine visiting the Galapagos with anyone other than Quasar and have recommended them to all of the friends and coworkers that have asked about my trip.
I stayed in D4 my 2nd trip and C6 on the first trip. I was only in the cabin to sleep but it was comfortable, very clean, and had everything I needed. There was plenty of room and storage.
