I can't find the thread but I remember somewhere someone asking about hosting a private breakfast at WM the day after the wedding at the Hyatt in Garden City. Below is all of the information.
'If you would like to host a Private Breakfast, that can be done in our Meeting Room. The Rental fee is $350.00++ with the Block, and the breakfast can be provided by you, or the hotel can recommend a caterer to you. If you would like the hotel to provide the caterer it is $19.95++ per person, and the food is brought in from an outside company. We do not have catering facilities onsite. This room can seat up to 60-65 guests comfortably, and you have the room for 2-2 ½ hours.'
Personally, we won't be doing this. There is a complimentary breakfast so FH & I will just put a range of time we will go down for breakfast on the OOT welcome letters and people can meet us if they would like.
