Welcome home!
Do as Kathie said, take your time. Initially, it will be fun setting up your new home, but doing it day in and day out will get tiring. Set up your kitchen, clothes closet and your bedroom.....then when you find something you want to see or do....go, do it! You'll have clothes to wear, a place to eat and a restful place to rest your weary bodies.
Enjoy settling in, but do recognize that there are many here who still haven't fully unpacked...
