I'm inviting several out of town guests (including FI's immediate family) and will need to reserve a block of rooms. How far in advance do I need to do this? Is there a down payment required? Those of you who also have done this, who did you go with or who do you recommend? My wedding is at St. Elizabeth Ann Seton church in Bear and the reception is at Executive Banquets in Newark/Glasgow, so I'm looking more towards the Newark area. TIA!
