We went to the Galapagos a few years back, and we stayed in Quito a couple of days on both ends. It was fun, but not necessarily an exciting place. Same with the food - it’s good, but we found nothing great. The beer is ok, but the wine lists are minimal and expensive. Will mostly be Argentinian and Chilean wines as well (not that there is anything wrong with that). Avoid the Cuy - deep fried guinea pig (tastes like a deep-fried rat).
Roaming the old town area is fun. If you’re into pre-Columbian artifacts, a couple of good museums. Also, the Olga Fisch store is nice, and the family has what I would consider to be a museum, upstairs. Go to the shop, and ask to see it. The family has a large collection of artifacts.
You have to stop and get a hat: Homero Ortega Panama Hats - Cuenca, Ecuador Shop is in the Old Town area. Plus, a lot of shops sell some of their hats. We stayed at some kind of Marriott (I think) and they sold their hats.
The gondola ride to the top of the mountain is fun for what it is.
There are a couple of competing places for where the real equator is. Both are tourist traps, but, whatever.
I’m not making Quito sound that great, but we did have a fun time. Again, most fun was just wandering the Old Town area. Lots of little shops. Quaint architecture. Decent places to eat. Lots of colonial architecture.
We actually did a Celebrity cruise, but it was on one of their smaller ships. Probably less than 100 people on it. Friends did a bigger boat, and were not as thrilled. Also had friends do as small as a 25-person boat. In one case it was with National Geo, so it was top-rate, but top-cost (I guess you get what you pay for - they loved it). Another friend did a small boat that was no thrills. Got essentially the same guides, but at night, it was pretty minimal. But keep in mind, going between the islands, you’re out on the ocean. Their complaint was that they got rocked around, but in a small boat they also did not cover as much ground. In the bigger boat, they hit fewer places because they were too big to dock. But just about every island, you’ll have to be tendered.
Bring a camera. Bring a camera. Bring a camera.
Bring sunscreen. Bring sunscreen. Bring sunscreen.
Dress to go hiking in a wet dessert. Some islands are like walking across Mars, and in some cases, you’ll have to wade water. Try to at least snorkel so you see the turtles and penguins. Get some local coffee off the islands.
The Galapagos were absolutely one of the best trips we ever took.
