I think there are two options,one get a friend to find out from travel agents on package tour since you only mentioned your mum,I think its better she travel in groups. Second, book and pay hotel on line and let her find her own way there. Why don't you suggest to her to scout or talk to local travel agents. She can decide when is the appropriate time and number of days,stuff like that. If she is in KL, they are many local tours organize by local agent. Even on news paper, like Star or Malay Mail you will get to see a lot of advertisement. I am sorry I am not in Malaysia either if not I will help and find out what other option is available. Early wish to your mum 50th birthday,Happy Birthday and God Bless!
