As a kid that grew up in Las Vegas the Excalibur has always been around. My father helped open the Hotel and I've had several family members work there in years' past. I've gotten a chance to eat at almost every restaurant they've put inside that place at one time or another.
Hell, I practically spent a good portion of my childhood in the Fantasy Fair downstairs LOL. Anyway as time moves along things change. Obviously, anyone that has been and reviewed the Excalibur has stated the obvious; the hotel & casino are dated. The rooms aren't modern or sophisticated, the table games and slots are old and cheap. The restaurants are all three star or below, with the exception of Sir Galahad's, which is now referred to as "Pub" and Prime Rib... classy.
Excalibur is good, cheap, three-star fun and entertainment. I'm not sure how long this "seasoned" hotel will last in the new world of Vegas, but if you have a chance stop by and enjoy an old favorite of mine.
