So my 8 year old son is obsessed with Legoland. He would even rather go to Legoland than go to Disney which is just insane to me. When we first moved to England in July 2018 we quickly purchased Merlin Premium passes which is good for Legoland and a handful of other attractions around England. With the pass you can get a hotel discount, food discount, merchandise discount and free parking. We often stay nearby in Slough but also use the discount to stay at the Legoland hotel occasionally also.
Today, we are staying at the Copthorne Slough-Windsor about 10 minutes away. Bonus is they have an indoor pool and hot tub, quieter than the Legoland hotel and a Chinese restaurant my husband likes.
Today for the first time since we started going the Star Wars mini figure area was open and it was AWESOME.
