Gifts for boyfriend?? HELP

So my boyfriend makes a lot of money. Like 3-4x more than I do. Easily. He buys me lots of gifts and takes me to hotels for weekends sometimes.

I am not very materialistic, but obviously love the gifts and weekends away. I am just looking for ideas of things I can give him/do for him that would actually be worthwhile and not something he could just buy himself.

I want to show him that I love and appreciate him.
