Weddingbee boards

Bees, we need suggestions where to honeymoon for relatively cheap.. We are getting hitched August 4, 12, But will be taking the honeymoon the first part of December.

We went to Belize last year and it was A-MAZING! We want an adventurous location with hiking, snorkeling, beach. In Belize, we stayed in a jungle for 4 days, rock climbed, hiked, and then flew to an island and relaxed on the beach for 5 days.

Considering the following:
New Zealand
Costa Rica
Dominican Republic

We are open to any ideas and locations, except Hawaii or Mexico.

Please share your experiences!

Thanks,

Under $4,000 and we will stay as long as our budget allows!  Preferrably 8-10 days.  In Belize, we stayed for 9 days and total cost was approx $3,000 for 2 including flights, lodging, food, activities, etc.
