Hi Lesleyg!
Welcome to the forum. As Phil and Eileen have said, if in doubt just ask, we are all familiar with the layout of the village, and the accommodation in the village.
A lot depends on what you are after when it comes to 'independent' of 'package' deals. There are some bargains in the package holiday if booked quite a bit in advance or 'late deals' as in last minute, but I find as an single traveler it works out better for me to book independently. Most 'package deals' are based on 'two sharing' with a nasty sting in the tail for the single traveler with the 'single occupancy' supplement. Most establishments in Arillas, do not charge this 'rip off' fee, as the money you pay your host goes directly to them, and not as in the case of the 'Travel Company' who pay the hotel a fixed fee/day and pocket the difference!
As Eileen has said, have a look at the map, there are a lot of places near the beach, most of the premises are bookable both ways.
Martin.
