国庆节期间你准备去海南度假.请你写一个旅游计划.

we are planning to go on a vacation during the national day with my parents ,so i made a plan .
we plan to leave for hainan island on 29th by plane,we may stay there for about 5days ,we want to enjoy the sightseeing there and playing on the beautiful beach ,we expect to go fishing beside the blue sea.it must be a great day .i could't wait anymore .
as we all know ,our envoronment is polluted a lot ,so i should do something to help as i have a chance to go to the hainan island ,so i decide to join the volunteers to pick up litters during our vacation .
it would be the most excited experience that i can't forget!
