Hi everyone me and my husband are doing a mini honeymoon in January now my question is which hotel is better for a mini honeymoon ?
Castle Hill Inn is much better than both of the two you have listed. You can also rent private cottages on the beach at the Inn. You would want a car for this location.
Of your two, I would pick Gurneys but it would be far lower on the scale from Castle Hill.Also would want a car here.
The Marriott is very nice and if you stayed there, you could walk to the local restaurants.
What are you looking to do? Location wise, 41 North is more walk able to places on Thames and the wharfs....smaller boutique hotel and at times can be a bit snooty. Although in January it probably won't be as bad. Gurney's is a bigger resort style hotel but should be pretty quite after the Holidays....they offer a shuttle into town or you could take a walk if the weather isn't too bad.
If you are looking for romantic, I'll agree with Emily about looking into Castle Hill.
