Masters - Practice vs Sunday

Super lucky to have won lottery and just received my two Sunday tickets in the mail for this year’s tournament. I was very fortunate to go to a Tuesday practice round in the past.

Anybody ever been both? How different are the experience? Other than the obvious rules that only apply during tournament round (e.g. no phones out), anything I should do differently on a Sunday round?

We went to gift shop first thing on the Tuesday practice round and walked around afterward. Is that still the move? Isn’t there fewer people walking around?
