My wife and I are planning a trip in the Maldives this coming November. We are planning to stay 3 days in a hotel in Maafushi and 3 days in a resort in Thulhagiri. Is there any restriction in changing habitation to Maldives due to Covid?
You will not be allowed to move between islands, you are only allowed to stay on one island for the period of stay. I doubt you will be able to visit Maafushi either as for the time being only resort islands are open for tourists.

It's allowed to travel between all tourist facilities unless they are not under monitoring. But you have to apply for permission. It can be done by your hotel (actually, it's the only way) and free of charge. It's not a problem to get it.
