The OP's first sentence says it is a travel team. That alone sets more than enough expectations for a trip of 2 1/2 hours or more.As a coach you completely skipped over how and when you decided to play 2-1/2 hours away.
Was it completely up front from the beginning, or did you change your mind later.
That is the key here. Nothing else matters.
Especially at 10U, some players and parents are strapped for cash. For the coach to up and decide on his own that we need to travel 2-1/2 hours away and get a hotel room, and time off from work, is a big question.
Only you have the answer. The other posters do not have a clue.
