If you are not set on going to Breckenridge, I would recommend Salida, CO over the July 4th week. They have a wonderful fireworks display with the fireworks being shot off over the mountaintop. They have a great little park at the edge of town along the river where everyone congregates for the fireworks show. There's also lots of shops & such downtown. We took a group of Jr. high youth with us. If I remember correctly, we went horseback riding in nearby Buena Vista and used Noah's Ark River Rafting company to go whitewater river rafting (also within a 30 -45min. drive) I hope to go back with my own child once he's a little older. Another bonus is that Salida is closer than Breckenridge if you're driving from TX. Sorry....I don't have any suggestions for where to stay. We were on a mission trip & stayed in the local middle school gym. :)
