It depends if you are talking about going to the Seattle and Houston Regionals or the Seattle Regional and the Houston Championships.
Both Regionals -
If you sign up for both regional events and don't have funding to pay for registration and travel to the second regional you don't get to go.
Regional and Championship -
First, to attend the Championship you need to meet the FIRST requirement to register for the event (see FIRST website). If you think you have a chance to "Win" the Seattle regional (regional winners qualify for Championship) I'd start fund raising NOW! It would be a shame to not be able to attend because your team hadn't raised the fund to travel. And if you don't need them you have a great head start on fund raising for the next year.
