I had a reservation in Nov 2018.... I am from Oahu but was bringing my family from florida to Mauna Kea.
Subaru cancelled our tour last minute, didn't offer any help finding alternatives. We had to cancel our Big Island trip, pay fees to change last minute to Maui. Went to Haleakala instead.
We again made reservations this Month April, but again had to cancel because they only had Japanese tours available. All of my emails ignored, never responded to.
I was given a supposed direct number to someone in Hilo w/ Subaru who could help. Called for 3 days, no answer and voicemail full.
Don't Center your trip on a Subaru Telescope tour, they will cancel at any time and become impossible to reach.
