I can not do that where I frequent. All but 1 dd game is no mid-deck entry. It is also dealt face up. But to get back to my point. I am not aware of any DD games that allow you to start with 2 hands drop to 1 then pick up 2 again that has no mid-deck entry. I always get backed off when trying that. Which is about 20-30 times a trip. I always hope they let me do it
I don't know where you play, but almost every casino (98%) allow you to drop a hand out and add a hand back even with no Mid-Shoe Entry rules in effect. It's only if you drop out completely that you cannot re-enter the game until the shuffle.
