Hello,
As far as checking in to resorts in Punta Cana ..... Generally speaking .. what day is the most busy ? I want to book another trip,but I feel like I would be more likely to be bumped or moved to another resort on a busy day.
After the next couple of weeks the low season is coming. The hotels won't be sold out and you will have less of a chance of getting bumped. Coming from Canada the busy days are usually Saturdays and Sundays. Not to sure about other parts of the world.
