Wow! Where do you begin? My pre cruise expectations were that Allure would just be an overhyped, scaled up version of RCL's other ships I had experienced (Mariner, Explorer, Independence). How wrong I was. It is as if RCL has taken all the best bits from the development of resort size ships and enhance them in a more sophisticated setting (I never imagined referring to Allure as sophisticated!). Allure has everything you expect but with the size and class to separate the varied areas making it a ship for a very broad range of customer. Everything was very tastefully presented and not as "tacky" as I thought it could have been.
If you can't find your personal niche on this ship you should avoid taking a cruise altogether. Generally the organisation, given the sheer scale of things, was amazing. Prebooking for shows and activities works better than the free for all you can find on other ships and the wide range of such entertainments allows freedom of choice. Food, whilst not gourmet, was fine given the typical cost of a cruise but unfortunately I was afforded the opportunity to sample the numerous upscale restaurants - which looked fantastic.
I would recommend that you try Allure - Whilst you may still have other personal favourite ships you will come away from this experience in complete awe. Allure is magnificent!
