I did Club MoBay on arrival back in April and there was no line at immigration so it didn't save us any time (on a Wednesday, arriving at 11:30am). Just a few weeks ago, I decided not to do Club MoBay as we were trying to save some money. We waited in line for 1.5 hours to get thru immigration (on a Wednesday, arriving at 1pm).

We did TimAir a year or so ago and it was awesome! 12 minutes from MoBay to Negril. Now of course, that is once you are in the air. I didn't time it to see when we got to the hotel, but after you get thru immigration and customs, you have to check in at the TimAir desk. They then walk you over to the arrivals terminal and we had to wait a bit for the plane to come in and be ready for us. Gave us time to get a couple red stripes. You then go thru the security scanner (nothing like going thru the regular security line!) and walk out onto the tarmac. Up in the air and you are back down before you know it! We had a driver waiting for us at the Negril Aerodome to take us to the hotel and grab some necessities.

I wish I had the extra funds to take TimAir every trip!
