I would leave less than one if possible. Booked an excursion in Oahu. I realized immediately it was wrong date. Supposedly you can cancel within two hours. After being on the phone for an hour with a woman who had no clue what she was doing or talking about she disconnected me. Called again and next lady told me tour operator office was closed and they would send email for refund and to call in morning. Surprise called in morning and they would not refund my money after arguing for another hour and having proof of my calls and that timeframe was within two hours. Horrible customer service. Lost $150
