No laundry facilities on site that I know of, but you can call to ask. Very sparse amenities at this location.

No there is just the basics - if that. Very minimal.

An additional thought re: pets in National Parks. Their access to hiking trails and geyser or mud pot viewing areas is very severely restricted. You might want to check the restrictions and determine whether your pet might be happier in his or her own home with a friendly dog sitter or neighbor looking after the pet.

We did not need any heat, but I do recall the A/C thermostat showing heat as well as cooling. The little grill at the General Store did offer some breakfast and light lunch items, faster and more convenient than the restaurant, but dinner was very limited to take-away food at the restaurant. The first night I had a Bison burger which was VERY but the French Fries were stone cold so better to grab a bag of Chips. My wife had trout which was also tasty, moist and flavorful However the second night we both had the burgers, which were way over-cooked and dry. We had not specified (and were not asked) how we wanted them cooked, so specify when ordering. And if you have any back problems, be sure to ask for a ground floor room, or help to carry your bags as there is no elevator and ca 20 steps to carry the luggage. But be aware that WiFi on the ground floor is pretty much non-existent.

The Park gates are always open. There won't be anyone to take your money, but you can pay on your way out.
