If you reach Pinnacle during a cruise, you are recognized as reaching Pinnacle status at the Top Tier event. However, you do not receive Pinnacle benefits until your next cruise. We reached Pinnacle on our cruise 2 weeks ago and Diamond + benefits were in effect.
We were on Symphony last month. It was 7:30am when the announcement for self-assist was made. There was a line for the self assist walk off. Other consideration is traffic to FLL and airport lines. Seems very risky.
