Been looking around for holidays to Cancun, Mexico. About 6 of us are going to go around June/July. We were thinking of doing an all inclusive deal, but I've never used any online holiday packages before so dont know which sites are the best and which ones are reliable. Was wondering if anyone could recommend some. Also do any of you have any past experiences of all inclusive holidays, are they worth it, or would you advise against them and book everything seperate?
