I agree with you about the condition of Negril Escape. The rates are cheap, but they are cheap for a reason. A great alternative would be Home Sweet Home. All of the rooms have been recently updated, and you get all the same amenities as Negril Escape (you have to pay for breakfast, but I always thought the free breakfast at NE was kind of weak). Plus, HSH is closer to MX3 where the Bob Markey Birthday Bash is being held.

During high season, you can probably get a standard room for less than $99. I know the advertised rates are higher than that, but those prices were set by the previous owners, and the current owner (Charlie) will give you a better deal if you contact him directly.

If you don't mind staying across from the cliffs, you can get a decent rate at Seastar or Catcha Gardens. Both places get positive reviews.
