Sorry for the late reply as was overseas trip. No they have a standard rate for the rooms but if you coming in a tour group I am sure they can offer you a discount for more rooms being booked. Just send an enquiry to the front desk to negotiate for a better rate before you book your stay there.

Hi Mickeyma, The cultural shows are on only certain days. I think they are closed for Sundays due to church services. But the outdoor museum is open all the time so if you are a history buff you won't miss out on much. But to keep it safe bet going there on a weekday will be the safest bet.

yes they do... no probelm with walk in visitors. payments by credit card or cash. i went ad hoc... no pre booking etc.. it was not a peak season .

Yes they do have day tour option and I believe you can walk in even without reservation (which we did 5 years ago) but now we usually do it online. For day tour you can enjoy the buffet and can also swim at their designated pools.

The weather is quite cold every night and will get colder until February. I believe aircon will not be an issue. Electric fan will do the trick if in case.
