Decisions!! Need advice!

Hello! I’m a senior who is having trouble deciding between five schools for different reasons. I want somewhere where I can get a great science education, but also have a comfortable, nurturing environment, and opportunities for internships and travel abroad. I’m deciding between Caltech, Johns Hopkins, rice, Dartmouth, and Carleton college. Any advice or experience is much appreciated! I’m not leaning towards anything right now and and I need to decide soon! Thanks so so much in advanced!
