Hi Dubgirl
The Minimarket on site ie beside the sales office on the way to the Clubhouse, which is very well stocked and well priced, is open until 8.00pm at least if not 9.00pm on a Sunday. If you wish to email them (theminimarket@hotmail.es) they will make up an order for your guests and you or your guests can pay by card or cash. The supermarket Eroski at Dos Mares is open on Sunday evenings but it is really busy then and car parking is at a premium so your guests might prefer to get the basics in the minimarket and get their other things the following day when the local supermarkets open again and there will be no problem getting parked or standing in long queues after a flight.
A lot of my clients use the Minimarket ordering by email and find Sue and Paul really helpful. It is a great facility to have on site and is being operated for the owners and residents of Roda so it is good to support local people doing a good job.
Hope that this is helpful.
