Just enjoy it hun! Mr Singh is a boobie god, I love the man! Hehe 
Just remember things like comfy clothes, snacks, drinks (although you get food and drink there) but just in case you get peckish!
magazines, toiletries etc! Just make sure everything is in easy reach for you, and just take it as easy as you can, get some ready meals in and like pizzas and stuff for the first few days as I was so tired and drained you really don’t feel like doing much apart from sleeping! Lol
Just relax and enjoy it! Mr Singh will give you lovely boobies, you are in amazing hands! Good luck xx
