Greetings dear friend, traveling is a great way to relieve our mental fatigue. You feel comfortable traveling alone. You bring up the good points that even if you enjoy the calm natural environment alone there will be no one to help in an emergency. Traveling alone costs more than we can enjoy less. Group travel on the other hand makes for a good time to clear our mind of all the worries. Traveling in a group reduces our expenses a lot. You want to go to the sea in a group, friend. May your travel ideas succeed. Wishing you success in the competition.
