nice seats and drinking exotic juices. [Last] of people were dancing and the
music was playing loudly. We were having a lot of fun! When the ship arrived in
Honolulu a man was waiting to take us to our hotel. The hotel where we were staying
was by a beach lined with palm trees. Drums were beating and  people  on the beach  were singing and dancing to the music. The music was getting louder until I could hear a ringing in my ears. It was my alarm clock! It was 7 o`clock and time to get up for school.
