We tried staying here last week, while on an extended travel trailer trip with our kids & two of their friends, through Owens Valley and the Sierras. It was snowing when we arrived in Mammoth and we thought ithis place would be a great option, because of the rec room that they advertise, plus hook-ups and a laundry room. We arrived and my husband paid for two nights, then asked about the rec room and was told that it was closed because the owner was upset because someone had vandalized it (how about putting a coded lock system on the door, or simply not advertising it anymore?). We were worried about the prospect of staying in a small travel trailer for two days, with young kids, cold weather (in the 20's) and steady snowfall, but decided to give it a try. We unhooked the trailer and tried connecting all the lines and then realized that we only had electricity, but no water (or sewer, but we already knew about the lack of sewer hook-ups). We went to the office and asked the receptionist for a refund, and the owner walked over to the counter, and was incredibly snarky with us. She finally agreed to give us a refund only if we left "immediately." We had explained that we were upset about the rec room being closed, despite the fact that they advertise it as being available, and explained that was what drew us to her RV park in the first place. I explained that with 3 young, energetic children and a teen, we had been looking forward to the rec room, and that I couldn't fathom being stuck in our small trailer for two days with them, because of the snow and cold weather. She then chastised and scolded me, telling me that I should be ashamed of myself because I was on a family vacation and that I should want to spend time with my family in the trailer, and that she had four children of her own. She was incredibly rude, nasty and snarky. My husband, who is usually very calm, reserved and diplomatic, told her to stop being snappy, and to just finish up so that we could get out of there. I had told her that we decided to rent a condo instead, and she said, "Well, you are going to pay at least what you would pay for 3 nights here for only 1 night in a condo!" (Like it was any of her business!) I was so shocked and pissed by then, that I left my poor husband in the office alone to deal with her and to collect the receipt for our refund. We left and decided to stay at the Westin, instead, which probably costed what we would have paid for 5 nights in her glorified parking lot, without running water, sewer hook-ups, or even a picnic table or firepit (just plain asphalt!), for just 1 night at the Westin, but it was SOOOOOOOO WORTH IT after putting up with her crap! Everyone was so kind and friendly and professional at the Westin. I'd rather stay in the parking lot of a market or booondock in the middle of nowhere, rather than throwing money away to stay at an "RV Park" owned by a discourteous, contentious, unprofessional and snarky individual.
