Live Aqua Honeymoon

Going to Punta Cana in May for my honeymoon.

Staying at Live Aqua as it looked to be a chill resort we could relax at.

Our flight gets into Punta Cana around 10,

Check in is not until 3- any advice?

Also- in a junior suite right now, but thinking we may want to upgrade. What is the best way to do that?

Also, excursions? Best way to go about that?

Thanks for all of the help!
