Ibiza 7 day holiday from Bournemouth

So far, 8 of us are booked on a 7 day Jet2 package holiday staying half board in Santa Eulalia, Ibiza and flying from Bournemouth airport. I've chosen October as typical Ibiza weather is likely to be sunny and warm but not hot at this time.
I will be hiring a MTB for myself for the full 7 days. Plans for while we're there can be very flexible, but I'll be using the bike to explore the island some days, just for local excursions to the beach, etc. on others. I plan to take a ferry day trip to Formentera one of the days. I expect we'll be doing things individually some days, as a group on others.
Everybody joining us needs to book their own holiday, bike hire and travel insurance. Ask me for precise details of the holiday we're booked on or for any other information on 07922 168992.
Please, either bring your own cycling helmet with you, or buy/hire one on the island, and wear it on all our rides over there.
I'll be very pleased if a few other members would join us.
