I get that you feel like missing another potential win but trust your instinct, if you feel like need to take a break then it's fine just go with it, although I might say try a few more low wager bet on highest possible wins like slots since you are saying you are on a hot streak and if you don't win anything then you can convince yourself that the luck ran out and the break is justified.

Casinos don't want a player to stop, especially after winning and you are just following what they want?
