hi,
are you going to get a travel cot from the hotel or are you bringing your own?? either way, i would have her sleep on a (thin!) blanket or 2 that you can bring with you & lay in her cot - if it smells more like home she may not care that it's not her 'usual' crib.
try not to stress too much - try & go with the flow as best you can, so YOU can relax too. at that age, i would try to keep to her nap times as much as possible.
at night... i don't know how you feel about the security at your hotel, but in the past i have brought a monitor with me & kept the receiver downstairs so i could hear what was happening in the room. i have also hired a sitter to stay in the room while we go out.
