Hi Jami,
I am not sure if you mean you are buying a 1-day 1-park ticket for 7 different people or tickets for 7 days for yourself. There are lots of ticket options available.
If you are buying 1-day 1-park tickets for 7 different people there is no break in price.
If you want tickets for 7 days for yourself, you can save yourself a lot of money buy purchasing them all at once because the price per day becomes less the more days you purchase. For example, as of 1-14-10 (this is
always subject to change without prior notice), a 1-day 1-park base ticket is $79.00. If you purchase a 7-day 1-park ticket, the price is $234.00 which averages out to be $33.43 per day. Again keep in mind prices are
always subject to change - I just wanted to give you an example.
You can also add the park hopper and / or the no expiration date options to your tickets (each option has its own additional charge). Multi-day tickets base tickets without the no expiration option, expire 14 days after the first day they are used.
If you are planning any future trips, buy as many days as you can afford and add the no expiration option. It may seem like a big investment in the beginning but you save yourself a lot of money in the long run.
