Havana, January 26 (RHC) –- In light of diplomatic talks between the United States and Cuba, Responsible Travel has announced that inquiries to its most popular Cuba holiday plan have doubled.

Responsible Travel, the leading comparison site for small vacation companies, has announced that a 15 day cultural tour of Cuba is the most asked about holiday of 2015 so far.

Inquiries in January for the trip have more than doubled compared to last year and interest in the holiday is at an all-time high.

The dramatic increase comes as the relationship between the U.S. and Cuba is reported to be becoming friendlier, with Barack Obama calling on the U.S. Congress to end the more than 50 year economic blockade against Cuba.
