The driver was very friendly, and the two local guides (one at bromo and one at Ijen) were also very kind and took many photos for us.
The package covered all the key places and never felt too rushed.
Unfortunately, king kong hill was pure fog, and the blue fire wasn't visible, but that was due to local conditions and no fault of the tour. We still ended up seeing some fantastic views inside the active Bromo crater and of Ijen's blue lake and burning sulphur.
A very enjoyable tour overall.
