We will be in Dubrovnik in late May and we would like to take a couple of day trips. Unfortunately, 2 of the trips we would like to take with Atlas are scheduled for the same day.

Is it possible to go to a TI and book similar trips with other agencies while we are there?

We would like to go to Trsteo, Peljesac Wines and Vineyards and the Elaphite Islands.

Are there other agencies that off these excursions?
Thanks for your help! Laurie
