If you're able to get away to another resort, I would highly suggest it. The reality is your friends and family are going to be so excited for you both and are undoubtedly going to want to spend time with you if they see you walking around the resort. We spent the day after the wedding with our group but then headed to St. Lucia for a solid week of Mr. & Mrs. time. It really is nice to have that time to connect after being the host of such an amazing week with friends and family. You'll be the superstars to everyone which is fabulous but it also calls for some hosting responsibilities. If you're anything like me, I was never completely able to turn off the, "I just want to make sure everyone is having a good time" feeling (I mean, how couldn't they be...they were in paradise!
No matter how much I worried, everyone was having so much fun - it didn't warrant the worrying that I did. This is also why having some extra time with the new Mr. will be important - just to decompress, talk about all of the excitement of the week and enjoy each other before getting back home. I'm pretty sure we spent 90% of the time on our honeymoon, laughing and reminiscing about the week of friends in family - all in one place to celebrate us. It'll truly be amazing and rest assured, it'll all work out no matter what!
I'm not sure if you're looking for a more "romantical" option to spend a few days, but I after doing our Trash the Dress shoot our photographers (Del Sol) suggested we spend a few days at Le Reve Hotel & Spa and it was like we were worlds away! Here's my review below if you're interested (with pics!)
Best of luck and remember, it'll all be perfect, even if you have to see Uncle Bob at breakfast the next morning :-)
