We have contacted some hotels that offer deals and are practically located for the wedding. Renting a finca or a private house is also a great option.
Please contact us for suggestions or if you need help.
In any case, airbnb.com, abritel.fr and booking.com will surely have more. We recommend you, though, to stay in the area of Es Migjorn, Santo Tomàs, Son Bou or Alayor so that you are not too far from the venue or the bus shuttle stops.
