Reviews: From NYC: Washington & Philadelphia Full Day Guided Tour

Guest User2026-04-02

Diego is an excellent guide – fun, energetic, and full of interesting information that makes the trip even more special. What really stands out is his creativity: he has music prepared for every “wow” moment and plays it at just the right time, which truly elevates the whole experience. He even acts like an FBI agent at times, adding a unique sense of humor and originality to the tour. He is very professional, as he says every sentence in English and then in Spanish, so everyone can easily follow along. Even though the trip includes quite a bit of driving, the scenery and overall experience are absolutely beautiful and worth it. Special praise also goes to the driver, who was excellent – safe, pleasant, and professional throughout the entire journey. Overall, highly recommended! Greetings from Croatia 🇭🇷
