Gate 1 Travel river cruisers are budget-conscious travelers originating primarily from the U.S., Canada or Australia. Each sailing boasts a mix of seasoned travelers along with less frequent travelers -- even some first-time visitors to Europe. While river cruises are generally most appealing for travelers aged 50 plus, ages and income levels vary.

A little. In keeping with most river cruise lines, Gate 1 Travel does not impose any kind of dress code on its river cruises. The onboard vibe during the daytime is relaxed and casual. Most people change for dinner and wear something a little smarter, but jeans and casual tops are perfectly acceptable. At the final night captain's gala dinner, some passengers choose to dress in smarter attire.

No. Fares include one walking or coach tour in every port, basic Wi-Fi in public areas and a choice of red and white wine, beer and soda with dinner. Aside from water, which is freely available at every meal, any drinks ordered during lunch are at extra cost, along with beverages from the bar. Additional optional excursions also carry a fee and gratuities are not included.

Shore excursions are the no. 1 activity for Gate 1 travelers, and while the included options are almost always full, the extra-fee choices are also popular. Onboard, cruisers tend to congregate in the lounge reading a book or chatting with other cruisers.

Best for: Mature, budget-conscious river cruisers; fans of Gate 1's land tours
