Ive just received notification from Art Cafe that Montenegro Lines dont offer this fast boat service from about 1 month ago. Its a shame as it was a fast way to get between these 2 places(4 hrs) and something I was going to try.
Other options are the regular boat trips which the fare is P1500 per person and it takes 7-8 hours. It wouldnt be my preferred way to travel between these 2 destinations due to how long it takes and its on a smaller vessel and depending on ocean conditions it may not be a pleasant trip.
Food for thought.
