I am planning a trip with my three kids (ages 5,5,6) and my parents. We are thinking of spending 3 days on the big island after 4 on Oahu (my parents met there 46 years ago and have not been back so it is a must). Anyways, my children definately want to see the volcano and I have been looking for best place to stay. I have seen several private homes for rent near the park but was wondering if I should stay somewhere else and drive to park. I was also wondering about best snorkling. I am concerned about snorkling in Oahu as we will probably go in June or August and I have seen precautions due to stinging seaweed and jellyfish. If anyone has good ideas of places to stay and how I can make this a fun and educational trip for my kids and a wonderful memory for my parents please let me know. There will be seven of us traveling and I need the most bang for my limited buck!!
