Do you need to return own rental car first?
If not - about 1 HR + time at the airport. The airlines advise 3 hrs for international flights.
No, we will be doing a private transfer. 4 hours is what I was as thinking but wanted to check with folks who had actually been there before in case there was something I wasn't thinking of.
Yes you are correct...is about 1 hour ride...good roada...even two hours prior the departure you can check in...jus relax...and good point ask people that reallly know the area first hand that is a great idea.
