If I am planning on staying in Macau for 3 months on holiday, what type of visa do I apply for?

The application form provides 3 options:
1)Valid for single journey of 14 days within 3 months
2)Valid for double journeys within 3 months, 14 days of stay per journey
3)Valid for multiple journeys within 6 months, 14 days of stay per jouney

I will be staying with family, but I wont be doing too much travel...which one of these is appropriate for me?
