Yes, considering our personality before traveling is very important. Some people are introvert while others are extrovert and this should be in check before going in group travel. Friends could be annoying during this time and it could change ones motive for a journey. I believe group travel has more fun than solo. Solo is expensive and time consuming because you need to plan alone, but with group, it saves time and cost. I enjoyed lots of fun the last time I was on a group travel. Your place of recommendation is nice. Success to you!
