I went there with DH shortly before covid. We unfortunately experienced a freak unseasonable tropical storm that made the trip less fun. That time of year should have been beautiful but we couldn’t see many views through all the rain.
If I were to travel anywhere any time soon, I’d be likely to book a group through GAvdentures. I’ve traveled with them a few times and really enjoyed it. They would help with any covid rules/test/etc. It costs a little bit more than booking on your own, but I generally also get more out of the trip and learn more. And I really enjoy traveling with a local person. The groups are small (like around 10 people) and usually include a few solo travelers, a few couples, a student or two, etc. It’s nice to have someone handling the logistics so you can spend more time doing stuff and less time fiddling with a rental car. This is especially nice when I only had a short window for travel because I had to get back to work. I loved traveling with them in Cambodia and Laos. Finally, this is also a great option for traveling with friends or family. Nobody is responsible for logistics or blamed if a hotel turns out crappy. Whoever wants to go simply signs up and you go have fun.
