Planning a honeymoon and wedding in SLP Masters

My fiance and I are planning our honeymoon for October 2023. We don't want to spend too much but we also have had to cancel 2 trips in the past two years because of the Pandemic and my school schedule for my masters program so we have been saving. He likes the idea of a more relaxed honeymoon and would be ok if everyday is a beach day, but I definitely want to also go do things too. We want to be able to hike, bike and snorkel, he wants to scuba and I would like to be able to do a horseback ride together too. We are planning on a two week trip to an island, but would prefer a shorter flight. We live near Boston, and I am looking for advice because I start looking and get overwhelmed because of how many beautiful places there are. We were considering St. Lucia because of the hiking. Any recommendations?
