This is my response on the other forum that I left for you, so now you have two.
We are flying from Toronto to Panama in February for 2 weeks and we are staying at the Royal Decameron. Just to give you an idea on cost, we booked an Ocean Front, Ocean View room on the beach, which I believe is the top room for the resort. We also booked Club Class on Air Transat and the total cost for each couple is approx. $5,000.
The Royal Decameron was our first choice because of the amenities it offered in the way of choice of a-la-cartes, number of pools and bars, disco, casino and within walking distance of a few restaurant/bars on the beach (Woody’s which is owned by Canadians).
I hope this helps somewhat and you can make an informed decision by speaking with your travel agent and looking at the tripadvisor forums and resort reviews.
