Finding a good companion to travel with can be incredibly difficult. You want to travel, but you haven't found the best companion to join you. Most tours and cruises charge an additional fee called a "single supplement" for travellers who want their own hotel room or cabin. Sometimes these fees are minimal. Other times, single travellers can end up paying double. Here's some ideas for lowering the costs of travelling solo.
Escorted tours/Group Tours
These tours offer the safety and companionship of travelling in a group, but the flexibility to go off and explore on your own. Some groups are specifically designed for singles travel. For instance, Globus offers has a single share guarantee - they will find a roommate for you so you don't have to pay a single supplement.
Avalon waives the single supplement on some cruises. Norwegian Cruise Lines offers reduced single supplements on some sailings (150% v. 200% of base fare). The NCL Epic revolutionized singles travel by introducing the singles studio concept. The Epic has singles cabins located around a special lounge for just the guests in those cabins.
As a travel agent, I have special access to information on which cruises have a reduced single supplement and which group tours are the best fit for single travellers so be sure to contact me for your next trip.
