I've only done package holidays with Jet2 before and they give you a "voucher" for the hotel with all your details to hand over to reception at check in.
Do easyJet do the same and I've missed the email, or is it specifically a Jet2 thing, and I won't get refused check in at 10pm when I arrive? I'm just thinking back to a previous holiday where I hadn't printed out the voucher and the woman at reception got very shirty with me, I had to find the email and forward it to her so she could print it out before we could check in, was all a bit stressful, and I could do without any more stress ATM
