Depends on what you like. I'm sure I'd love parts of Hawaii away from the tourists and beaches. I absolutely loved New Zealand when my wife and I did a three week road trip across the country for our honeymoon, especially the south island. The swiss alps were also very beautiful.
I went to Bermuda last year. The water was clear and warm. It has pink sand beaches. We went cliff jumping and spent hours in the water every day. It's the first time I actually swam out far off a beach because my brother in law assured me the Northside of the island didn't have sharks. Also it's much closer than Hawaii.
Part of Hawai'i being so gorgeous is that you don't generally get to see massive lava fields and beautiful tropics and above-clouds massive mountains with perfect night skies all in one relatively small island.
Keeping an eye on this thread because my fiancee and I are planning to go to Hawaii for our honeymoon. The islands look beautiful, but also seems to be very expensive (food, accommodation, etc.).
Depending when you're coming from and how long you're planning on staying it's really not too terrible! We love Kauai and have gone probably 3 or 4 times, most of those trips we stayed well under $3k for everything. Still a lot of money, but not as high as people think.
I live in California and hate being stuck on a plane, so Hawaii is really the easiest destination.
Hawaii is good as long as you do your homework. They've been hosting tourists for many decades, so if a resort hasn't been doing regular renovations it can be a real dump.
