Pacaya volcano hike Guatemala - which operator and are the marshmallows still a thing

Going to Antigua in January and obviously want to hike Pacaya. Couple questions for anyone who’s done it recently:

  1. Which tour operator did you use? I see a bunch of options on the hostel boards and online and honestly no clue who to trust.
  2. Is the “roasting marshmallows on lava vents” thing still possible or has the activity changed since the recent eruption activity?
  3. How hard is it really? I am not in great shape (desk job, maybe 2 hikes a year) and the horse rental option scares me a bit too.

Any honest takes appreciated. I don’t want to be the person holding up the group but I also don’t want to skip it.
