we've stayed here twice, in the world tower and story tower. personally i prefer the world tower. all the staff was very accommodating and helpful. room prices are competitive given the location on the strip and the amenities. we want to try the luxe tower and will most likely be back in a few months. we had some trouble with our reservation being lost however so far they have handled it well for us.
for this trip our rooms were in the world tower. the room was nicely decorated and very comfortable. the restroom was sooo much better than the one in the story tower. i don't mind that its so far north on the strip since we have quick access to the monorail. upon check-in you receive a code booklet with plenty of vouchers (including a complementary 24hr monorail pass).
