Can anyone tell me where the best place is to book trips from?
We are staying at the Majestic hotel at the north end of Sunny beach.
We normally use local agents instead of reps.
I can't give you any specific recommendations, but you will find excursions being advertised virtually everywhere in Sunny Beach - in shops/booths/at the roadside, etc., so you won't be lacking in choice.
Whether all of the options are adequately insured, have English-speaking guides, etc., is another matter......
