I did this on our last cruise back in January 2019 and it is worth it. Think about it this way. I got 7.5% advantage on my initial buy-in to go up against the house with. I bought the $1000 and got 1075 in promo chips. I got them to give me a clear chip tray and $200 in $5 chips $100 in $1 chips and the rest in $25 chips. As I played, I would pull back every real chip to the tray and kept coloring up as it filled up with payoffs. It took me 2 good nights of play on a $10 blackjack table to finally burn through the chips. At the end of the trip, I was up around $300 after tipping etc. We are going back this November and I plan on doing the $2000 option so it will give me a 10% advantage which is 2200 in promo chips. As long as you are disiplined and only play with the promo chips, it lowers the house edge % wise for you. Hope this helps.
