It was my last, last minute decision to go out for the SH tour just 5 minutes before midnight before the tour, and they immediately responded and arranged for my tour on the next day.
My tour guide, Alana, was very kind and knowledgeable with her 10+ years of guide experience, and the first thing she did when we met was to create a personalized tour route according to your preference. Since I did not know anything about SH, Alana suggested 7 different spots, and apparently, we ended up with most of the key attractions in SH in a single day. She was very flexible and was able to change the course on the fly on your request and quickly figure out the arrangement in no time. Highly recommended!
