Ski Trip to Gaudari and exploring Tbilisi

Hello Georgian members

I am coming with a group of friends from Dubai in the middle of Feb.
We want to go to Gaudari as well as explore Tbilisi.

Your guidance, tips and advices would be highly appreciated.

We are planning to fly via Fly Dubai (arrive in Tbilsi at 4am) and would like to know easiest/best way to reach ski resort - any reputable companies to use. What not to do etc.. Can we manage with USD or must to have local currency etc..

Any recommendations for particular hotel/chalet in ski resort?

Wishing you a happy new year Protected content many thanks in advance.

Kind rgds
Dalia
