STAY AWAY !! I purchased 3 single kayak rentals on GROUPON. I made a reservation 2 days prior and was told the kayak's were available for the day of my reservation. I called the morning of the kayaking day asking for directions and was not told of any problem. I drove 45 minutes to get there with my family and when I arrived, I was told there were no single kayak's available. The receptionist told me that she has called me and left me a message, but this was a lie. She then told me I could have a triple kayak for the same money I had paid. When I asked to see the triple kayak, I was shown a 2+1 kayak which is really only suitable for 2 adults and not the 3 adults in our party. In addition, that kayak normally rents for much less than I had paid. I asked to speak to the owner, but he was not answering his phone. After about 30 minutes, I was told that there were no life jackets available so all the talk of taking a different kayak was a waste of time! I asked for a refund and was given a refund receipt, but later that night, the owner texted me to say that he could not directly provide a refund. I am still waiting on my refund. The owner also called me to apologize and offer a free rental, but if a paid and reserved kayak order is not fulfilled, can you imagine what they would do with a free one !!?? It seems to me that this outfit was able to rent kayaks at a higher rate than I had paid on Groupon and did so with no concern for me or my family. We wasted a day of our vacation which also happened to be the last day of our vacation. Despite making the reservation in advance, confirming twice in advance and paying in advance, they still gave away our kayaks and wasted our time getting there and back as well as more time trying to get us into an unsuitable kayak which in the end they didn't even have lifejackets for !! Even worse, we were provided with lies (left a message, gave a refund, etc). IMAGINE...they don't have enough lifejackets !!?? While I was in the store, there was another family there who had had the same experience as me and was there for fulfillment of their previous reservation !! There are other outfits in Kailua that rent kayaks. DON'T waste your vacation time and money with Windward watersports. Find another reputable outfit to do business with. The prices elsewhere are the same and you don't get the lies, aggravation, wasted time, false apologies and wasted vacation time!!
