I have actually decided to book rooms at multiple hotels since none of them rooms available for every day of the convention. I hope this isnt a bad idea.
that sounds like that could get complicated very fast - your CC might decline the charges [different hotels in a short time frame] might suggest your card is stolen so you better give your CC company a heads up ---
or again you really try to book a more consistent stay at one hotel only - but thats just my 2 cents.
booking different nights different hotels sounds like a checking in/out nightmare for you and your guests.... \
check out is usually 11am or noon --- and then checking into another hotel isnt until 2 or 3pm...
you sure you really wanna to do that to yourself and your roommates? there has to be a solution and the hotel registration team might be able to help. you should really try to contact them for advice.
