Hi, Can't help with the hotel or eating out as didn't stay there but we stayed at the sister hotel Rasa Ria, last February and had a fantastic time. We did stop on a coach at your hotel and looked very nice, we were on our way to the Klias wetlands on a trip very good trip. You see the proboscus monkeys, and lots of other wildlife.
There is a shuttle between the two hotels and would be worth you catching it to see the orang-utan sanctuary at the rasa ria as it is really good, you can stay and use the facilities as well, and the beach.
The restaurants at the Rasa Ria were about the same price as here to eat £20 per person for the buffets which were really good food.
The weather was very hot and humid with the odd heavy shower, mosquito's were not a problem but kept covered with deet spray.
I wore the same as I would here in hot weather really, dresses, linen trousers, skirts with t,shirts and blouses.
We did find it hard to change travellers cheques apart from in hotel, there is ATm's and cash was easy to change.
Lots of good trips to do, if you like wildlife, and scenery, as said the islands of Kota Kinabalu are lovely for snorkelling and peace.
The people are really friendly.
Have a great time we did.
Hope you have a fantastic time, we did.
