Hi - I came back from the Elysium last weekend. We had an ethereal room with side sea view and it was fantastic - it would be classed as standard, but I cannot imagine what else you would actually need!.
The room was very spacious, with king size bed, choice of pillows, TV, playstation, fully stocked mini bar, plenty storage, free safe, bathroom with power shower, stocked daily with Molton Brown toiletries, fluffy bathrobes, slippers, large soft bath towels replaced twice a day, complimentry wine and fruit in the room on arrival.
We looked over to the tombs of the kings, and could see the sea side on from our balcony. I preferred our view to having a room at the front of the hotel. It would have been nice to have a full sea view, but I couldn't justify the price, and it was getting dark by7pm so wouldn't have had much benefit from it!
Didn't get a chance to see inside any luxury rooms, but did see the daily butler service delivering wine and petit fours every day to them - not a priority to me when I am on holiday! I would have no hesitation in booking an ethereal room again -it was lovely, and since we were out of it from 8 - 6 each day and then again in the evening, any more money spent on the room would have been excessive and unnecessary!
