need info about drop location and cab services in gudauri

Hello
We are planning to visit Gudauri by Marshutka and we wish to stay near Gudauri Ski Resort. Where does the marshutka drop us while going from Tbilisi to Gudauri and where should we take the marshutka to come back to Tbilisi?
We read in some posts that the minibus leaves near Wisol or Smart Market.  The resort is uphill according to maps and the bus leaves somewhere down. Are there any cab services available                                                                                                                                                        Thankyou
