Crappiepappa, several have brought propane heaters, there has never been an issue with them if you want to bring yours. I just bring two electric heaters so that way i don't have to supply propane. We have been on the park Manager for a while now to fix or replace the heaters in there with no luck. believe we may have to take the next step soon and involve some higher powers. It really isn't that bad in there dinobot, especially if the fish are stacked in there. You forget all about being cold.
