You'll find that there are a variety of different room block options in Las Vegas. What I've generally found is that there are two types of blocks, typically at no cost to you if it's a big strip resort because they'll fill their rooms anyway, and often not free if it's a smaller resort or off-strip where they have to fight harder for their room commitments. With that being said, here is typically what you'll run into:
- (Big Strip Resorts) - These typically require nothing more from you than your wedding date, an estimate on the number of rooms you think your guests will consume (and feel free to over-estimate) and your contact info. Most often, you'll get the number of rooms you request if it's a reasonable number and then they'll tell you that they will only hold the rooms until 30 days prior to your wedding date. You'll get a group booking code in the email and that you'll need to share with your guests. The way it works is your guests will call in and be able to book a room at the negotiated rate up to 30 days prior to your wedding date, even if the entire hotel has sold out for some reason. The group rate will rarely be as good as what guests could get on their own online when combined with coupon codes, however, if the hotel sells out, or the guests really do wait until the final six to eight weeks, chances are it will at least be less expensive then what they could get at that point, and it guarantees them a room. So the best way to use a room block is to tell guests here's your room block code, it's good until X date, the rate you'll get is $YZ and here's some coupon codes you should use instead if the date is not yet X.
- (Smaller resorts and off-strip resorts) - These will sometimes work like the above, however, not always. Some resorts will charge you a deposit fee for the block which will be refunded to you, or applied to your own room, once a minimum commitment of rooms has been met. So in this case, you have to be a lot more careful about the number of rooms you estimate your guests will use, because your guests may stay elsewhere, or you don't get the numbers you expected, and if that occurs, you could lose your deposit. If you do meet the commitment, then you get your money back. These types of blocks will usually have better pricing than the option above, due to the financial commitment, but still not as good as coupon rates, so estimate carefully.
