There is a current resort map recently posted on here (you will need to do a search for it). We have stayed there 4 times and prefer to stay in the original Bella Florida section (previously called Garden Section), buildings 4-9, as this is away from the construction, but a good location in terms of views etc. The Keys section for us is too far away from the main pool, but then again you may prefer a quieter location. The amelia section is the newest section, some buildings are already in use (with no dedicated pool area etc) and some are still under construction (which I think is behind buiding no.s 1-3).
Hope this helps, and enjoy your stay. You can ring beforehand and request an area or indeed try for a building number, and also request a high/low floor (they are only 4 floors and all buildings have lifts).
