Whilst there may be romantic anticipation of a wonderful time away together, be careful to ensure you actually do share the same interests and desire to travel to a particular destination. If one partner's dream is to go rock climbing in New Zealand's South Island, whilst the other hates camping and is afraid of heights, that trip may well put sufficient stress on the relationship to bring it to breaking point.
In such circumstances, I strongly advise couples to go their separate ways to their respective dream destinations and reunite reinvigorateded, inspired and still loving each other.
Those of us who are single are actually at at genuine advantage. We are free to choose to travel either alone, or with someone who genuinley shares similar interests and has the same travel goals with much less baggage than if we were in a more permanent relationship.
Most recently I travelled across parts of Europe and Turkey, with a dear friend who shares my own passion for history, art, architecture, gardens, photography, wine and food. Our trip remains amongst the most positive and enriching travel experiences of my life.
From the start we agreed to go our own way should we want to explore different attractions to meet our own interests within a specific place. However, our need to do this was the exception, rather than the rule.
When it came to finances we agreed on a budget relating to accomodation and living expenses. Instead of contributing to a travel kitty, we actually found we could keep track of our expenditure share by taking it in turns and balancing expenditure out, rather than deciphering and attributing every cent as we went along to the last decimal point.
We were tolerant and considerate of each other and truly enjoyed each other's company both before and during our trip, returning as good a friends as we had been prior to our departure.
If you are considering travelling with another person, be they a long term partner, or a friend, it may be worth your while reading my "traveller profiles" blog posts. Consider whether your proposed travelling companion falls into one or more of these categories and how well you will function as positive travelling companions.
The best travelling companions not only share a lot of common interests, they may also complement each others short comings. If one is excitable, the other may be a calming influence. If one enjoys navigating and using maps they may want to take the lead in locating key attractions. The other may spend more time researching accomodation. One may have some command of a foreign language, whilst the other may have less or none. Things balance out!
Never be afraid to travel alone in the absence of a travelling companion you anticipate will travel harmoniously with you. Way better to pay "the singles supplement" and have a wonderful time as a solo traveller, than to compromise a friendship or long-term relationship as a result of conflict whilst travelling!
