DEFINITELY need a good 4x4 vehicle or newer 2WD SUV to access the property. Georgetown has the shops you'll need to get groceries and other goods but expect a 20 min drive into town from the property. We recommend purchasing your own groceries for part of your stay because, the only restaurant on the lodge charges more than anywhere else we ate at.
We stayed here and the amenities and cabins were awesome with proximity to some of the most famous Mayan ruins in the country. The cave tour is great as well as the quietness and friendliness of the family that owns it as well as the employees.
They did however have complications with booking and overlapped bookings in our cabin. They asked if we could leave a day early and said they would reimburse us. The last night, though everything was cordial, they gave us half the amount we agreed upon in local currency and said they'd PayPal the rest. We have yet to see the reimbursement and they are unresponsive over WhatsApp which almost everyone uses to communicate.
