Sandals Negril is under a major renovation right now. About one half of the total property is being rebuilt from the ground up. Everything from the main restaurant north is under construction and appears about 1/2 done. The suite that you rented is far removed from the construction and you shouldn't hear any noise. The suites are very nice and somewhat isolated. As for the ganja, I pretty sure nobody is going to care. If the neighboring suites don't care for ganja then you can walk just a few steps next door but be prepared to get hassled by locals.
