I just completed a trip from Probolinggo to Bromo and then on to Ijen. Both volcanoes are really great and I would recommend them. But i will not recommend the tour operator that I went with. His name is Toly and he was introduced to me by the manager of the Panorama Hotel. When we talked, the price, pretty high, was to be with 2 people to Bromo and only me to Ijen. But when I went to Bromo there was 5 other people in the car not 2 and to Ijen 2 more people. I found out that i paid almost twice as much as what the other 2 had paid for the exact same thing.............. So if you want to go to Bromo or Ijen and It is really beautiful, check around and do not go with Toly. Also the second driver we had did not speak much English and had a really bad attitude.
