I am moving to Hawaii from Texas. Help ! (General Knowledge)

Hi everyone I am a E-5 in the military and am PCSing soon to Hawaii from Texas. I did the math on my new paycheck but just wanna know if there are any other entitlements I should be aware of when living in this expensive a** state. I’m a E-5 AGR soldier and not married. Give me whatever information you can on living, what to do, eat, anything at all helps. This is my first HUGE move 🥴🇺🇸
