Can I access the facilities and pay for the services in Nexus Resort & Spa Karambunai even though I dont stay there? Or they are for staying guests only?

going to kk soon..any suggestions for a good hotel there? have reasonable price, clean room and most importantly no ghost

Not much activities at Kundasang, basically visit Mt Kinabalu National Park, Poring Hot Spring at Ranau(National Park entrance ticket covers Poring as well, but additional fee implied for canopy walk), Kundasang War Memorial Park, vegetable farms, flower nurseries.  Anyway, it's a good place to just sit back, relax and enjoy the cool mountain air and have some BBQ chicken wings for afternoon tea.  You might want to bring along some tit-bits, potato chips/prawn crackers and beers for the night. 

Have heard of Zen Garden but not stayed there. Have stayed at Rose Cabin, rooms with great view overlooking Mt Kinabalu.

thanx for ur info guys..act i plan to go Kundasang on friday nite, expecting to get beutiful sunrise there. but my fren said its not like semenanjung where we can easily drive during nite time.. so not recommended is it?  If dat so we just go early in the morning on Saturday. act i want to get some fresh fish or prawn to bring back home, filipino market should serve dat rite?
btw, any cntact number for car rental service?
someone suggest to go to labuan , anything special there?

Not filipino market but Pasar Besar next to filipino market. They do have packing service. But must pay for the sterefoam box and packing service.

Just arrive gaya hotel
Din know kk traffic can fight kl traffic

I went to KK last year.

It was awesome. I stayed at the Karun Bunai Resort (or something like this) and I enjoyed my time there.

The people there were very friendly as well.
