Looking for our dream honeymoon in the Caribbean

My fiance and I are thinking about going to St. Lucia or Antigua for our honeymoon, but are open to all Caribbean suggestions.

We are thinking Sandals La Toc for St. Lucia (the bluffs) or Cocos Hotel for Antigua. Has anyone been here before? What was your experience?

We have done some research and here are our concerns

St. Lucia: people talk about the horrible drive to and from the airport and suggest nausea medication.. are they being dramatic?

How bad are the bugs?

Antigua: Beautiful views but not a lot to do or places to eat in the resort.

Also open to other suggestions if you have them! Thanks in advance!😊
