we loved our stay last year in the lowlands with the only drawback being the drive especially to Gran Case for dinner
the villas are so beautiful, you never want or need to leave
May I suggest chef Franc to prepare a dinner for you, we enjoyed a multi course lobster dinner which was not much more than going to a restaurant and you can provide your own wine, we pretty much went all out with grand cru wines to pair with the food
And while Sandy Ground is not our favorite, we noticed no rif-raf while traveling through especially the idiots on cycles as there was a check point immediately after passing through

We have no reason to pass through Sandy ground this year

for some reason I always like to fill up the gas tank at the Cadisco just past Nettle Bay which is considered Marigot
food food shopping we go to the Super U in Marigot but certainly Maho market or the Carrefour in porto cupecoy would suffice

Never met a bakery I didn't like but O Paris in Maho near the Dunes casino and Morgan resort was extremely limited
Pretty sure there is still a bakery in Nettle Bay

Probably closest would be the renamed Jules in Jordan village or maybe just as close Ferdinand bakery in Marigot which has the Pistachio cream croissant that I had a quest for
