St Lucia has stunning scenery and beaches eg Anse Chastenet and Ti Kaye (on Anse Cochon beach). Anse Chastenet hotel has an AI plan and Ti Kaye has meal plans. Snorkelling is good at both these beaches esp at Anse Chastenet.

Grenada is also a lovely island with white sand beaches and blue sea, also has a range of AI properties from 3 star upwards and various villa accommodations. If you don't go the AI route there are plenty of restaurants.

Antigua has gorgeous beaches but the island scenery was not that interesting, stayed at Hawksbill due to the excellent location and beach but the food was not great. Galley Bay Hotel which is next to the Hawksbill is a step up, but there are several options around Jolly Beach which might be suitable.

PR is probably the only island I did not enjoy but then I only went to SJU.

Barbados does not have the scenery although the atlantic side is quite beautiful, it does have plenty of AI options and the beaches. Not much snorkelling, if any. Lots of other things to explore though.

Guadeloupe and Martinique have mountains, volcanos, snorkelling and very nice beaches but might be difficult to get to plus language & the Euro can put people off if they are coming from the US, which is a pity as they are spectacular islands with plenty to explore.

Tobago is hilly with lots of windy roads, has lots of beaches, some excellent for snorkelling. It is low key and untouristy, local people are friendly (Sunday School is a must). Coco Reef is an AI hotel, there are couple others, esp if you don't need 5 star food and accommodation.

Although I love Bermuda, not sure if its the right place to go in November (I went in July), also it does not offer the scenery nor the AI accommodation, plus it is a very expensive island.
