I'll take a shot at your questions and I am sure others will weigh in with their opinions. I've been in Negril in December and January and will return mid-Feburary so my experiences are recent.

Currency - I've never exchanged money at home, always do it in Jamaica. If you are lucky enough to have free ATM usage from your bank, the ATMs are the way to go as they give closest to the true rate, but if not exchanging at the Cambios, isn't a killer, just never exchange at the airport or with the guys in the roundabout in downtown Negril. On the free market you should get somewhere around 145-147 to 1 while the true rate thru the ATMs is 155. My hard and fast rule is to carry both currencies and if the place you are frequenting prices in J$ use those, if they price in US$ use those. The place determines the exchange rate and it's never close to the true rate.

Airport - We've never used Club Mobay except once during the height of the pandemic when we had the kids with us so 4 persons and we knew the health protocols would be nuts. We arrive early typically so get out of the airport quite quickly. Best advice is sit as close to the front of the airplane as you can and walk quickly past others on the way to immigration. It just depends on when your plane arrives as to what the airport will be like. If you are that worried about it book Club Mobay as it is a very reliable service. We always take a private taxi but I have plenty of friends that use JUTA and recently as busy as things have been they have filled up quickly according to those that have used it. The airport and the traffic in general between MoBay and Negril is a crapshoot. Just drink a few Red Stripes along the way and get into the Jamaican groove and you will be good to go.

Stuff to see - if you are out west end that is a sight in itself, a trip to the Red Dragon is always on my list and one of my first dos of any trip. Make less plans, get in the groove, let it come to you and you will be fine. If you visited Negril a long time ago things will have changed a lot, but some things will be the same. You've made a good decision to return, I truly hope you enjoy your trip.
