hi again, it's very safe to be in Phuket as travelers, group or singles. things to be aware for since you & friends are "Asian females" can be that you may be mistaken as local Thais, hence the western males can't distinguish the difference culture between us, thus don't be surprise if you get invitations for drinks, dates or sex from europeans sex tourists. you can walk every where in Patong, but if you need to go outside of the town, the only mode of transport is run by the Mafia, they are called Tuk Tuk, and you will be shocked on how much they will charge for a short travel of a few km. It's not cheap, and really there's no other alternatives for transportation unless you hire a motorbike and drive yourself, if you are comfortable driving on 2 wheels & have a license. remember to wear helmet, or you will get a very big fine from the police. Have fun though, and please be careful on the beach, this is our surfing season, so lots of waves and strong undertow; very dangerous for swimmers.
