Summer Reading Ideas

I'm going on a trip in a few months and already trying to plan my book-load! I don't know whether I should take the paper books that I have that I've been meaning to read, or whether to splurge and purchase some eBooks for ease of travel!

What are your strategies for books when traveling? I never estimate correctly how much reading time I will have and either take way too many books or not enough...at least if I choose to take my Nook I won't have that problem!

Happy summer reading to everyone!
