I was worried about such a long tour day with so much time in the van, but it was worth it to see beautiful Nicaragua! We were escorted through the boarder and always felt safe with our guide. We got to see so much more than I expected - not just a hop across the border for a passport stamp. The boat tour and views of lake Nicaragua were stunning, as were views from Mirador de Caterina and the walk up to Cristo de la Misericordia. Grenada and the chocolate factory was a little underwhelming in comparison and would have loved to tour the volcano instead (which was closed for safety reasons), but we were able to buy some coffee souvenirs there. The WiFi in the van on Costa Rica side was great but we switched to a different van on the Nicaragua side which didn’t have WiFi and password posted. The van wasn’t overcrowded, but seats did become uncomfortable for such a long day of sitting.
