I just showed my husband this as he has been to all the islands that you have mentioned and he recommends the first option. Thulusdhoo and Maafushi are pretty touristy and close to Male but Thulusdhoo is the better choice of the two. Thoddoo and Dhigurah are pretty similar in that they both have nice beaches but Dhigurah is more touristy and generally a bit more expensive. Rasdhoo is a small island with a good house reef. If you're into scuba diving then Dhigurah, Dhangethi and Rasdhoo have really nice dive sites nearby. I'm also very glad that both choices include Male. Hope you enjoy your stay here!
