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

Guest User2026-03-15

The trip was superbly organized, very punctual, and packed with amazing experiences in a short amount of time! Diego was perfect as our guide! His English and Spanish were excellent! Our bus driver, Roberto, got us everywhere we needed to go in three major cities safely and quickly! Fantastic! Keep up the great work!!!

Reviews: Small-Group Tour inside US Capitol & Library of Congress/Court

Guest User2024-07-26

Our guide James knew every person in our small group almost immediately and personalized the experience for everyone. Tons of firsthand knowledge from experience as a Capitol guide and living in DC his whole life. Told stories to teach facts with background and context as well as witty asides. Our group had folks from AZ, NC, KS, MO, Iran, Austria and China! Just a great experience!!
