This is a lovely Spanish break which explores two of the Balearic islands, Majorca and Menorca.
The dates are from 30th April until the 8th May and you will have 4 nights on each island.
30th April-4th May
You'll fly with Ryanair to Majorca. You will use Hoppa.com to transfer to your hotel which is the highly rated Apartmentos Cristina in Calla Millor. Once there you could hire a car locally or use buses to get around Majorca.
On 4th May yoh will take the ferry from Alcudia to Menorca. You could get the bus or transfer cheaply to Alcudia from Calla Millor. To book the ferry you will need to wait until they go on sale (similar to rail tickets), however there are numerous ferries a day to and from the islands and will take anything from just over an hour up to around 3 hrs depending on which one you pick, however the price doesn't vary too much and I checked a few different dates. The screen shot is just an example but you'll need to book this closer to the time but it should be a similar price and there are a few different ferries each day.
Once in Menorca you will stay at the highly rated Apartmentos Blancala in Cala Blanca for 4 nights. Again yoh could rent a car locally if you wanted to explore rather than take a car over the two islands as you'll be hit with a one way fee. Your flight back to Birmingham is on 8th May in the evening so you have a full day.
