Oh you shouldn't be nervous at all....you will LOVE Tensing Pen, it is a beautiful property.
I would highly recommend Ivan's at Catcha Falling Star for your anniversary dinner. They are right next door from Tensing. Call or email ahead and get a dinner reservation and let them know it is your anniversary and they will do something nice for you, sit you at the special table maybe even decorate it like they did for us.
That is a nice area of the cliffs as you are near some good places. Across the street from Tensing Pen is Ros Roddys, he has great soups and other vegetarian options. Head up the road for Ricks Cafe for the entertainment of cliff divers (but I would not recommend eating or drinking there, overrpriced and not so good
LTU Pub,just past Ricks, has the same great scenery but with much better food and drinks and A LOT cheaper.
You can see the Lighthouse which offers some pretty great views
If you head down the cliffs you can visit Rockhouse and Pushcart, at the Rockhouse hotel, beautiful property, also great places to eat. Eddie's De Bar across from Rockhouse has some great jerk chicken and some really STRONG rum punches LOL
Further down you have 3 dives right on the cliffs with some great jerk chicken and grilled lobster at good prices. Next door is Xtabi, a nice place with caves to explore and also some great dining and drinks.
Seastar inn is also very close to Tensing Pen and is a must do for their Saturday night buffet and live music

So as you can see, no reason to worry, you will have a blast!

Any more questions, just ask!
There will be plenty of boardies there in February, very popular time to go!
