I am in a pickle

I have 4 days of my trip still unbooked and I thought I would be fine and I would book cheap cabins as my budget for those 4 particular days is close to zero but I did think if a low cost all inclusive came up maybe I would push the boat out a bit and consider it.

The dates are 26th-30th December

Where can I have as a back up if the cabins are not available?

I know a lot of you are going to be there at this time and have all been getting quotes so if you could please message me or post your deals here.
