Recs and advice for 11/09-15/09 🙏

Hi all, my friend (23F) and I (35F) are coming to Ibiza 11th to 15th September. It's her first time on the Island, so we're going to nights where she thinks she'll enjoy the music. I've warned her about the crowds!

We're out for a good time, to dance and have fun, but also enjoy exploring during the daytime too. So, we've a few questions we're hoping you guys can help us out with on our current itinerary 🙏

Thursday 11 September: Land, check in in Bossa, head to Amnesia. Do we need tickets in advance, or can we get on a guest list for this?

Friday 12 September: Explore Dalt Villa, find somewhere for lunch/rooftop drinks, and chill before Ushuaia and UNVRS. These were a must for her, so we're sorting tickets in advance.

Saturday 13 September: Day trip to Formentera - we're looking for recommendations for a fun boat trip to take us there and back, and for where to make a lunch reservation 🙏 We fancy a beach day, then plan to hit Hi for Black Coffee. [Although I desperately want to try to get to Chinois for Claptone, too - is it possible to do both? 🤞] Is this another one to get tickets in advance for?

Sunday 14 September: Day trip to San An. O Beach, walk around, watch the sunset. Then Pacha for Solomon.

Monday 15 September: Rest, recover, and catch our flight home to Manchester at 2315. Can we fit in a hike somewhere nice (if we're not wiped out)? If so, where would be best to find a decent route and some stunning views while we're probably not at our most energetic? Or would we be better finding a beach club?

Any recommendations or advice you can share would be really welcome - thanks! 💛🙏

Also, one more question: is ticketsibiza.com a legit site to get tickets from??
