"I've been on 13 trips with STI and I've had a great time and met a lot of wonderful people on all of them. What I really like is the STI process for encouraging togetherness which includes (1) members meeting the day before the trip to have drinks and dinner so that when you start the trip the next day you feel comfortable with the other members, (2) a Breakfast Club for members who want to meet for breakfast, (3) Happy Hours each night before dinner, (4) eating together each night, (5) Theme nights for members , and (6) separate excursions for members. Another good feature of STI trips is the concierge who makes arrangements and schedules activities and helps to resolve any problems that occur."

"We booked a National Geographic expedition Holland and Belgium by River. The promotional literature promised a 14-day deposit refund window. The “invoice” was marked “non-refundable” deposit. We completed the National Geographic Traveler Information. About 8 days later we received the “Travel Agreement” to be signed. We both approved and signed the National Geographic documents. A Cruise Line Travel agreement was enclosed but had no signature line. This document contained language which was unacceptable. We submitted the signed NatGeo documents. The following day we canceled the trip due to the unacceptable Cruise Line language. Cancellation was made 12 days after booking and no deposit was returned. We were told on the phone that the refund deadline was triggered by the 14 day window OR signatures on the Travel Agreement which ever came first. This was NEW information. To date, we have received NO refund of our $1000. We cancelled our trip within the advertised 14 day window."

"I've traveled with this company 4 times and find the value and service outstanding. If you are on a slim budget try the " last minute" opportunities. We got an incredible deal on a river cruise two months out."
