Jan 2019: same holds true on marina and staff. But, amenities need work. WiFi was awful. One dryer malfunctioning and no sign indicating. The marina office was 95% empty of drink/food items/supplies. If this is to be a full service marina, need to step up your game.
We stayed at Thunderbolt for couple of days. The Marina was clean, bathrooms were clean, laundry room was clean but only one washing machine was available (other 2 were out of service). Staff very helpful. We also needed parts and service from Thunderbolt - all the personnel were wonderful. Had our parts within two days.
