I would do research on these places princess! Some of these islands… well there is only “islandy” things to do there such as swimming, snorkling, kyaking, deep sea fishing, diving, sailing, going out on a boat, etc. And if that is what you want to do - then that is great! Some people prefer to islands because its pretty lowkey and just visually stunning.
I have heard lots of wonderful things about the bahamas tho. You should check out the “Atlantis Resort” … its supposed to be amazing! Plus if you go there, u have to go to “blue lagoon island” and take the tour … its where all the dolphins are at! 
There is horseback riding on the beach, and there are gardens for you to stroll in where there are tropical plants and birds.
The only reason I know more about Bahamas is because my fiance has already been there … 
So obviously that is not going to be on my list of places to go… But he absolutely luved it and recommends it to everyone.
Turkey is really nice too… u have the beaches and the city life to explore. It is a nice blend of east and west and you will have no problem finding halal food to eat. The food is delicious from what I have heard. There are a lot of historical things for you to see, shows you can attend, and ofcourse SHOPPING that you can do!! Side note: They luv pakistanis. You can get great bargains and deals. 
My fiance has been to turkey a few times too …
There is tons to see and do in Italy ofcourse. The obvious reasons are there. But the drawbacks are that one can get sick of eating the food (vegetarian pasta and pizza) and it is super duper expensive.
Yup. You guessed right… my fiance has already been to italy as well…
Greece sounds like a beautiful honeymoon destination. One of my best friends is greek so I have seen her pictures from when she goes back to visit her family and heard her stories. Really really luvely. And again you will have the option of the beaches and the city life. So you can enjoy both.
Don’t know anything about Thailand But yea - i really suggest you research each place and see what kind activities and such there are. Make lists. Just google and it will be easy for you!
Good luck!
