Hi Marc,
What time of the year are you planning to go? This helps make the decision because it could already be booked during the busy season. Also, do you want a charcter meal? LTT is a charcter meal that my dh and I enjoy very much and he has requested again this trip. It's very much a meat and potatoes kind of place with great food in my opinion. I haven't had the pleasure of dining in the castle but hope to try that this year. I'm sure not matter what you choose you will have a great time.
Off topic, I have to ask is Hoffman Estates an actual town and was it developed by a group realtors by that name? Weird I know but my last name is Hoffmann and my in-laws are realtors/developers and I thought once I had heard about this. Thanks for letting me be nosy.
